I'm disappointed in myself

I tried killing myself again last night. Hanna called the police on me and they took me to the hospital. Everyone is so angry at me. They expect more out of me, but I just can't keep up with their standards. I don't know how to fight this and to be honest, I'm tired of it. I'm tired of myself, I hate myself. Every single day is like a war inside my head and I'm not winning. My future isn't bright. They're probably going to send me away.

They get so mad when I actually talk about what I'm going through, although they tell me time and time again to talk to them. My sister told me I was just imagining the voices in my head and that I was being silly and, "stop lying." I don't know how much more of this I can take.
