I dont' know what to do, and I feel responsible. I have had this one friend for over 7 years now but in the last 2 he's really started relying on my for everything. I love him, and we are like family. He's dealt with a lot of horrible things and is working on his depression right now. But what that means for me is that he calls or texts me countless times a day, and takes out his anger on me(verbally). We talk about how its not ok, and he apologizes but it never seems to change anything. So yesterday I told him I couldnt do it anymore, I was tired of being disrespected and I would not stand for it anymore. It has been effecting my own mental health, adn I know I have to look out for myself or I will spiral down. It didn't come out of nowhere because I've told him before that I couldnt keep putting up with it. I ended with I love you, but I just cant do this. I'm sorry.
I get a call today that he tried to take his own life, and he's unconscious in the hospital. The only note left to me. What am I supposed to think of this? I feel like I'm responsible, but I couldnt handle it anymore. Now I dont' know what to do. He's still unconscious but almost stable.

I am so scared to do the wrong thing, but I know if I stay I'll be doin myself damage. I can't handle if he doesn't make it or tries again because I'm not there.
I know there's no right answer here, but any advice would be greatly appreciated.
