Struggling with Emotional Exhaustion and Mental Abuse

I am emotionally exhausted. one minute my parents are fighting. next minute I'm sobbing. this is everyday. honestly I don't know when it will end. will it ever?? I can hardly get a job, and everyone is turning on me. I have a lot of trouble sleeping, and then when I do get sleep it's hard to wake up. I don't want to half of the time. so many things have happened. I would always get made fun of from like, 3rd to 7th grade. I have cried so many nights, because of fights, worrying about my family, getting into fights with friends, other stuff. I have been mentally abused and called names most of my life. it's tiring and I'm on the urge of just dropping dead from the stress. there's piles of it, EVERYDAY. NO MATTER WHERE I AM OR WHAT IM DOING! I'm tired, and I just want a good day, good enough sleep, and a family that doesn't fight and mentally abuse me. but I'll just keep dreaming. there's other stuff I don't feel comfortable sharing. but this stuff, that's not all of it. it's the beginning of a long story I don't know how to explain properly. is there any medication that can decrease my stress, anxiety, and depression and help me reduce my hunger?
