I give up

My life is literally falling apart right now. I have school I cant get a job unless I was to ditch school and get dropped from my classes because of conflicting orientation hours. My mother just lost her job with no given reason, my sister was just sentenced to serve life in jail, my brother is being threatened and harassed at school and i have no fucking idea what to do...i am losing my fucking mind and i have to help and be here for everyone else but i have no one to be here for me...i don't know what to do
