Dipper is a girl and does have a older brother but he Isn't gonna be in the story so far but he might come in later. Also I don't care that the video doesn't match the story at all XD.
This is what Dipper looks like:

To the story now:

Well, I heard there was a secret chord
That David played and it pleased the Lord
But you don't really care for music, do you?
Well it goes like this:
The fourth, the fifth, the minor fall and the major lift
The baffled king composing Hallelujah.

Dipper was staring at her bleeding arm. 'When did my life get so bad' she thought. She grabbed the knife that was next to her once again she cut.

'For living'
Cut
'For not being the person everyone wants me to be'
Cut
'For just being the horrible person I am'
Cut
'For loosing Mabel'
Cut.

She was about to cut yet another time but suddenly the door opened and Ford was standing there. A puddle of blood was on the floor next to her from the blood coming out of Dippers arm. Ford ran to her "what is wrong with you?! Why would you hurt yourself?!" He asked while getting me to stand up and pulling me to the bathroom. I didn't say anything and didn't look at him. He put my arm under the water from the sink. "Ah!!" I winced in pain. It hurt more then usual, I had cut really deep this time. "Sorry Dipper" he said. The water turned from clear to red then back to clear. Ford wrapped my arm up while I said nothing keeping my head down. He looked at me worried "Dipper why would you do this your not this kind of pers....."he started but then stopped when he noticed I was crying. "Dipper?". "I miss her" I said threw tears "I miss Mabel!!". Ford hugged Dipper "I know Dipper. I miss her too". Dipper cried in Fords arm holding him tight not wanting to let go. Ford was the only sane person Dipper could trust anymore. "How about you come with me today" Ford said. I nodded a ok as we walk downstairs. We saw Stan in the living room drunk as always. I could hear Ford sigh but he looked back down at me and smiled a little then we walked out the door. Wendy and Soos didn't stay here cause they had no reason to come back here since the mystery shack closed a few weeks ago. Ford and me were at the place we have been coming too. I looked down at a grave stone that read:

'Mabel Pines August 31, 1999'

They didn't even bother to finish her grave. I felt my fist tighten as I looked at it. I felt a hand being placed on my shoulder as Ford looked at me worried. I didn't blame him for looking worried, tears were falling from my eyes making my whole face wet "t-they didn't even f-finish it! Mabel d-deserves better!" I said a little mad but mainly sad. "I know Dipper" he said. That seems to be all he says now. The pain on my arm finally kicked in and I winced in pain. "Sorry Dipper I forgot" he said quickly moving his hand off.

Memory:

It was a few days after Mabel had died, Stan of course was drunk, to drunk if you ask me. I was downstairs siting down on the floor not doing anything when Stan got mad for some reason. He ended up throwing a beer bottle at me. It hit my shoulder, the glass going into my skin when the bottle broke. I fell to the floor I yelled in pain.
Ford luckily heard and came running upstairs to the living room cause he was in the basement. He saw me and the glass as he ran over to me "don't worry dipper it will be ok" he said as he saw me crying. "I-it hurts a l-lot" I said threw tears as blood came from my shoulder and onto the floor. I could tell Ford wanted to be mad at Stan but he stayed calm "Don't worry Dipper it will be ok" he said. He took me upstairs into my room. When we got there he put me on my bed so I was laying down and then took out the glass which hurt real badly, then he washed off the blood and wrapped the area up in bandages. I laid there still crying but I didn't do anything. "Try to get some sleep Dipper" he said then started to get up off the bed. I grabbed his arm and he looked down at me. "P-Please don't leave" I said. He looked at me for a second. "Your the only one I have left now, please don't leave me alone Ford!" I said louder this time as more tears fell from my eyes. I closed my eyes trying to make the tears stop but it didn't work. While my eyes were closed I felt something pick me up. When I opened them I saw Ford with his arms around me and I was on his lap. I hugged him. "I won't go Dipper" he said. I like this comfort, I never really ever have gotten comfort before, I liked how it felt. He wiped some of the tears off my face "it's ok Dipper, there's no need to worry" he said. I felt my eyes close and soon after I fell asleep.

Memory end.

"Ford?" I asked while Ford put down red and black roses in front of Mabel's grave.

"Yes Dipper?" "What's.......is there a meaning to life?" I asked. Ford looked at me and smiled a little "Dipper there are many meanings of life you just have to find them". I nodded. "Come on let's go home" he said. Mabel could still be alive but no one knew, she had gone missing long ago that people thought if she was still alive that she would be dead now. "Ford?" I asked. "What?" "Do you think Mabel might still be....you know.....alive?"I asked. "There's a small chance but she might be" he said. Once were at the shack we saw that Stan was gone. I found a note with sloppy handwriting on it.

I rolled my eyes and went upstairs. The first thing I saw was the puddle of blood from this morning. I didn't want to deal with that right now so I went back downstairs and slept on the ground in the corner of the living room.
