Please help...I want to just perish as a dream; forgotten upon awakening. Afraid to kill myself. How to live?

Yes it is definitely worth living. I usually don't answer questions but I want to help. But I think you just have to find someone to live for. Like your brother or the girl. I wouldn't want to live either if it wasnt for my boyfriend and I am 17. My family means nothing to me anymore except them giving me a place to live. My boyfriend takes care of me and teaches me life lessons. My family pretty much doesnt care about me. But I hope I helped you out. I'll pray for you.
