What do I do now..............?

I am so far beyond the point of stressed, depressed and pissed off that I don't see any solution. I've talked to a therapist, a counselor, my family doesn't give a **** about me, I don't have ANY friends, the only one who can even possibly give half a crap about me is my cousin. She's busy all the time, and if I told her anything, even though she is the only one in the world I trust, I'm sure my thoughts of suicide would get around the family in a snap. My mom has tried to commit suicide about 7 times before, but someone always finds her shortly after an overdose and calls 911. I have no money to go to a mental hospital, and I'm too young to do anything without parental consent. No one knows about my feelings or troubles because I don't talk to anyone, and I've been crying in my room since I got home an hour ago. I can't call a suicide hotline or anyone because my brother is in the room next to me and would hear me. I can't do anything, and I'm scared of dying, I just need all of this **** to go away. NOW. I don't know what else to do.
