If you want us to help at all with this, you need to write out as much of the transcription as you can (everything you understand), post it here, and then tell us the timestamp (minutes/seconds) of the parts you can't work out.
The clickable timestaps are in the video description so you need to open the youtube page to see them.

There's a lot here but here are the first few where you've put question marks. I'll try and do more later.
09:38 we had to end up in the hospital with her then through there
12:00 I just wish he'd knocked on my door, like, instead of chatting about it
12:10 I think it was a cry for help that went wrong
12:55 you're just ending your life really, innit? stupid thing to do
13:24 I know how it felt and it wasn't nice
(I'm not sure about the first one - it doesn't make much sense to me.)
