My grandpa collapsed about two hours ago. And now I am at a hospital.

Me and my sister went downstairs to have breakfast and we were having a good time. That's always how it starts.
I heard some gurgling from the hall and then I heard my mom scream. Me and my sister stayed put because we didn't know what was going on. I remember just thinking that my grandpa had either started vomiting or a worse thought, wich I knew wasn't the case but still. In the series Elementary: Season:2 episode:?? There was this man bleeding from his mouth. I knew that wasn't the case. Mom started screaming directions
" get two pillows!!"
" call 911!!!"
" go get help from the neighbors!!!!"
I started calling 911 but my grandma had beat me to it. My sister had seen what had happened to grandpa and I tried to avoid seeing that with all my might. My sister ran to the neighbors and I followed, and the neighbor had apparently heard what happened so he came over to help.
We heard heavy breathing and pained cries. And I kept my sister out of the house. We stayed on the porch for some minutes and I tried to get my sister calm and to make her stop crying.
Because if she was stressed then I would become stressed, and if I were stressed then mom would become stressed, then grandma would be stressed sooo.
I went back inside to get our shoes and then we left. When we came back home it was just my grandma there.
I assumed my mom and my grandpa had gone to the hospital. We later on took the car to check on him and that's why I'm at the hospital.
