Is it normal this happened to me?

I used to get all As and Bs in school. When I was 9, my best friend moved away and I got depressed. My grades started to drop, and my parents started emotionally abusing me, which turned into physical abuse a few years later.

Each school year, I made new best friends, but each time, I found out they were using me for there own good. When I found out, I stopped hanging out with them. Then, they hunted me down and sent me death threats. They made complex plans to get me in trouble. Once, my ex-friend framed me and got me banned from the playground for the rest of the year. Another time I was knocked out and left to die (outside). I have become mentally damaged after years of abuse from my peers and parents. I live in fear every day because there are people who want me dead. When I go home, I am abused. When I go to bed I either cry myself to sleep, hallucinate about a demon that tortures me (long story), or have nightmares. I am literally in pain with every step, because I self-harm my feet. I suffer at school, at home, and at night.

I have become a complete wreck and I've lost most of my ability to socialize, walk properly, talk properly, speak properly or think straight without remembering the pain I suffer every day. I also suffer from sleep paralysis hallucinations. Is it normal for people to become like this after so much abuse?
