Requested by americanarse: Y/N is an Avenger and has developed really bad PTSD as a result of fighting Thanos and the team losing everyone that they did. She overworks, doesn't take care of herself and tries to forget about it, but only makes herself more stressed in the process. She pushes back panic attacks and mental health episodes but Tony and Peter start to notice that something is wrong. One night, Y/N has a really bad panic attack, leading Peter and Tony to try and calm her down.

*Please note: as the requests suggests, this one-shot contains themes of mental health and includes a panic attack. First, I just want to say that I do not suffer from panic attacks and so please understand that if I misrepresent what a panic attack is like, it is not my intention to offend anyone or to misrepresent them. Also, if you feel like you will be triggered by this, as usual either please don't read it or feel free to message me if you read it and feel triggered. Thank you and enjoy :)*

Wanda and I fired our identical energy at Thanos, giving it everything that we got as we tried to take him down. Throughout the fight, Wanda and I had ended up being separated from the rest of the team with Thanos, meaning that it was now down to us to snap him out of existence whilst the rest of the team continued to destroy his army.

"Give it everything that you've got, Y/N, we're so close!" Wanda yelled.

"I'm trying!" I shouted back, my teeth gritting and my eyes squeezed shut in pain as using so much energy drained my body. I cried out, giving one last push to the efforts. And it worked. My energy pushed Thanos back, making him scream as he flew back, the gauntlet falling off of his hand and crashing to the ground as he was thrown back. I gulped as Wanda rushed to the gauntlet and picked it up, my eyes widening as she started to put it onto her hand.

"Wanda, no." I shook my head, tears starting to prick my eyes as it closed around her hand. She screamed out, her head flying backwards and burns shooting up the right side of her body as she absorbed the energy from all of the infinity stones. I choked and shook my head, my hands raising to cover my mouth as she looked at me with red eyes.

"Wanda, please don't do this!" I cried.

"Someone has to, Y/N. And it's okay that it's me. Vision is waiting for me." she gave me a small smile, but I could tell that she was in pain as tears also rolled down her face.

"Wanda, please. You're the only other person who understands the pain that comes with these powers." I sobbed.

"You're going to be okay, honey, I know that you will be. It was an honour to be your mentor." she nodded. I choked and shook my head, her giving me one last smile before she clicked her fingers.

"NO!"

My eyes shot open, a gasp leaving my lips as I jolted up into a sitting position in bed. I choked, tears rolling down my face and a thin layer of sweat glistening against my skin as I panted heavily. I bit my lip and held my head in my hands, my nails scratching at my skin as I tried to rid my brain of the horrific memories. It had been six months since we had won the war against Thanos and brought everyone back, including my best friend, Peter. But since then, to say that my mental health had deteriorated was a massive understatement. I'd developed serious and regular nightmares as a result of the trauma, my mind forcing me to relive the moment that I lost my mentor and motherly figure every single night. Sometimes even multiple times a night. I shook my head and swung my legs over the edge of my bed. I was well aware that the only way for me to suppress my panic attacks was to work out, and so that's what I'd do. I quickly got dressed into my leggings and sports bra, also grabbing a hair bobble to tie my hair up with as I opened the door and headed out into the living room and kitchen of the compound. Peter and Tony looked up at me as I walked in.

"Hey, kid. You okay?" Tony asked as he stood at the stove cooking breakfast. I ignored his question as I grabbed an apple, my mind all too aware of the fact that Peter was watching me from the sofa.

"Do either of you want to join me downstairs for training?" I asked as I took a bite of my apple.

"You're training again? You've trained every day this week, Y/N." Peter scoffed.

"We're Avengers, we need to stay fit." I returned.

"We also need to take breaks, Y/N. It's not healthy to be constantly training, our bodies can't handle that." Tony shook his head.

"Yours may not be able to, but mine can. See you guys later." I mumbled, my mind and heart still racing from the nightmare as I headed into the elevator.

Peter's P.O.V

Peter sat on the sofa, scrolling through social media on his phone as Tony stood in the kitchen and cooked breakfast. He looked up, his eyes wavering as Y/N walked into the room.

"Hey, kid. You okay?" Tony asked. She blatantly ignored his question as she grabbed an apple, Peter's gaze glued to her from the sofa. Since the team had defeated Thanos but had also lost Wanda, Y/N hadn't been okay. Though she'd probably die before she admitted that to the team. She'd gone from being a fun and relaxed person, to training by herself at every opportunity. She barely ate anything anymore and whenever she was asked by anyone if she was okay, she either deflected or just downright ignored the question. Peter's room was next door to his best friend's and it broke his heart when he heard her wake up with a scream. She was in so much pain, and it broke him that he couldn't seem to help. Peter and Tony knew that something was up, they just didn't know exactly what that was.

"Do either of you want to join me downstairs for training?" Y/N asked as she took a bite of her apple.

"You're training again? You've trained every day this week, Y/N." Peter scoffed.

"We're Avengers, we need to stay fit." She returned. Peter sighed and looked at her. He knew that something was seriously wrong with his best friend and it killed him that he couldn't help since she wouldn't open up to him. His best guess was some form of PTSD, but he could only speculate as to what was going on in her poor, in-pain head.

"We also need to take breaks, Y/N. It's not healthy to be constantly training, our bodies can't handle that." Tony shook his head.

"Yours may not be able to, but mine can. See you guys later." she mumbled and headed into the elevator. Peter sighed and looked at Tony, his mentor returning the look.

"She avoided your question again." he mumbled. Tony nodded and looked at the elevator that had now closed.

"I noticed. Something deeper is going on. Keep an eye on her, she won't admit that she's hurting but I can tell that she is. Make sure that you're there for her." he spoke.

"Of course, Mr Stark. I'll always be there for her." he reassured.

"Good. I'm sure that she knows that too, kid." Tony nodded. Peter sighed and returned it, his mind filling with worries about Y/N as he looked back down at his phone.

Y/N's P.O.V

"Wanda, please don't do this!" I cried.

"Someone has to, Y/N. And it's okay that it's me. Vision is waiting for me." she gave me a small smile, but I could tell that she was in pain as tears also rolled down her face.

"Wanda, please. You're the only other person who understands the pain that comes with these powers." I sobbed.

"You're going to be okay, honey, I know that you will be. It was an honour to be your mentor." she nodded. I choked and shook my head, her giving me one last smile before she clicked her fingers.

"NO!"

I gasped, my eyes shooting open and my body jolting into a sitting position in bed as I was harshly pulled out of sleep. I panted heavily, my heart pounding harshly against my chest. I tried to take deep breaths but my lungs only forced back out any air that got sucked into them. I choked and gasped for a single breath. I couldn't breathe, I couldn't get a single ounce of air into my body. My eyes widened and I looked down at my shaking hands. This wasn't good. Suddenly, my door burst open, making me choke as Peter ran in. His eyes widened as he saw the state that I was in.

"Shit, hey, it's okay, it's okay." he gulped as he rushed to me.

"Peter, I can't breathe, I can't breathe." I sobbed, tears streaming down my face as he scrambled onto the bed and pulled me into his arms.

"Tell me what to do, Y/N, how do I help?" he asked, his eyes still wide as he cradled me on his lap.

"I-I don't know, I can't breathe, Peter, h-help." I continued to cry.

"Fuck-FRIDAY, get Mr Stark here now." he demanded before looking back down at me.

"It's going to be okay, Y/N, try to breathe, I've got you, you're okay." he tried to reassure, his hands gently combing through my hair as he desperately tried to calm me down. As much as I loved him, it wasn't working. Him cradling me was reassuring me slightly but I still felt like my chest was being crushed. Suddenly Tony appeared at the still open door, his eyes widening as he saw me.

"Right, okay, listen to me, Y/N." he nodded as he rushed to my side and sat down on my bed. He gently took my face into his hands, making me choke and shake my head.

"T-Tony, I can't-."

"Yes you can. Focus on my eyes, you're going to get through this, kid." he nodded. I choked and reluctantly stared into Tony's eyes.

"Focus on my eyes and focus on my breathing. Breathe when I do, okay?" he encouraged. I gulped and nodded.

"Breathe in slowly...breathe out slowly...you're doing great, Y/N, breathe in slowly...breathe out slowly." he spoke. I followed his directions, my lips releasing shaky breaths as I breathed.

"Brilliant, keep doing that. You're doing great, kid, you're doing amazing." he reassured. I nodded and gulped, Peter's arms still around me as he gently rubbed his hand up and down my back. I closed my eyes, my heart starting to go back to a normal rate and air finally getting into my lungs.

"You okay, kid? Talk to me." Tony nodded as he gently let go of my face. I looked between him and Peter.

"What was that?" I gulped, making Peter look at Tony. He sighed and looked at me.

"That is what professionals call a panic attack." he nodded. My eyes widened.

"What?! How's that possible, I don't have anxiety, o-or any mental health issues." I scoffed.

"You sure, Y/N?" Peter asked. I looked at him.

"Yes, I'm sure." I nodded.

"Y/N, we don't think that you're okay with what happened when we defeated Thanos. I know that you've been against telling us what happened that night with Wanda, but this is eating you alive. I think that it's time to tell someone." Tony nodded. My eyes wavered, tears already pricking them as I gulped and looked down.

"Wanda died. And I couldn't save her. But, fuck...that night just replays in my head every time that I close my eyes. I can't escape it." I choked through gritted teeth as I shook my head. Peter sighed and reassuringly rubbed his hand up and down my back as Tony looked at him.

"Y/N, I think that you have PTSD, and it's affecting everything now. You train every second that you can, you're barely eating, you're not looking after yourself." he shook his head.

"Of course I am, I'm fine." I scoffed.

"Look, Y/N, I know how hard it was for you to lose Wanda, but you saved everyone else. So it's time that someone told you to take care of you." Peter nodded.

"I'm fine, Peter." I choked.

"No, no you're not. If you don't take care of yourself, I don't even want to think about what could happen. Think of all of the people, us, everyone who needs you and will need you in the future. None of us will have you if you keep doing this to yourself. Look, I suffer with this too. There are nights where I dread going to sleep in case some memories that I don't want to revisit come back up. But I get help for that, and I look after myself, because I know that people need me. We need you, Y/N." he spoke. I bit my lip and looked at him, tears rolling down my cheeks.

"You really have these thoughts too?" I gulped.

"We all do, kid. Occupational hazard." Tony shrugged and gave me a small smile. I sighed and looked at them.

"It's going to be okay, kid. But you need to acknowledge that this is a problem. There's nothing wrong with asking for help." Tony shook his head. I bit my lip.

"I just want to stop reliving it." I choked and shook my head. Peter sighed and gently pulled me back onto his lap, my head resting in his neck as he wrapped his arms around me.

"And we can help with that. We'll help you, I promise." Peter mumbled into my hair. I gulped and nodded before looking at them.

"Can you guys stay with me? I don't want to be alone when I fall asleep." I admitted.

"Sure, kid. We'll be here for as long as you need. Let's put on a movie or something." Tony smiled, making me chuckle and sniff as he shifted up the bed and sat next to Peter whilst I stayed on Peter's lap.

"FRIDAY, choose a good comedy for us. I feel like some laughs are in order." Tony chuckled, making Peter and I smile.

"Playing "The Hangover"." she spoke before the TV turned on and the movie started to play. Tony looked at us.

"I just want you kids to know that I'll always be here. You're basically my own children by this point, so you never have to feel embarrassed or anything to come to me, okay?" he reassured.

"Thanks, Mr Stark. That means a lot." Peter gave him a small smile, me nodding in agreement. Tony nodded and returned the smile before we all turned back to watch the movie. My eyes started to flutter shut, my body becoming overwhelmed with tiredness again. I let my eyes flutter shut, my body going limp in the loving arms of my best friend and in the presence of our mentor and father figure. Everything was going to be okay.
