Should having a crazy background make you crazy?

Okay so where do i start! I'm sure you don't want to know my whole life story, so I'll try and stick to the basics. I had sex with a girl when i was 9, she was older by about 5 years. At school me and my little friends were the most popular but also the most perverted haha! My older brother was 7 years older and was an INTENSE partier and pot head. He would have huge party's at our house on the river while my parents were out being gambling addicts and loosing all our money. That was the most innocent i ever was.

When i moved and grew into a teenager, life overwhelmed me. My dads an alcoholic, i listen to him throw up almost every night and now me and my mom think he has an ulcer.. he's dying. But the real sad thing is that my family's almost happy about it. We all hate him, we all agree hes ruining our lives cause his mental disorder. He doesn't work, he just gets all his money from his parents.

That brother i was talking about is now 22 and in jail cause he had a kid with a psycho b**** who's on 8 different meds and went to the mental hospital 80 times in one year. She reported him for something he didn't do.. just to get revenge and now he's stuck in the system. Since hes been in there hes turned into a religious freak, and is becoming someone i don't know. And hes our only chance of getting us out of this town we all HATE.

My mom was the most popular girl in her high school and was loved my everyone. She was raped 4 times, but never lost her spirit. Her dad, my grandpa, had a bad case of schizophrenia. He filled up a journal a day of "codes" he'd come up with. The code to god, and to life, and that the government is after him and blah blah. My mom would hang out with him on haight ashbury(a street where all the hippies partied in their movement)when she was a little girl. He tried to be a good father but was incapable. My mom swears on her life she saw him kill someone when she was little, and she would never lie to me.

My moms uncle was one of the worst cases of abuse in California and is now a billionaire. Him and a partner invented those nice retirement company's you see on t.v. But now he wont talk to my mom our anyone, cause he has this mental disorder where he cant have relationships with ANYONE. And if he would just give us a little money, it would change our life's forever.

Me, my mom, and other brother who's 2 years older, all do drugs together. But we do it to learn more about life, to open up our minds, and truly connect with things. Not just to get high.

Now were moving to another country, to escape from everything.
Life took me by a storm when i was old enough to care and realize what was going on around me.
I could go on but,
Does my family history sound crazy, or is it just me? and is it normal to be so overwhelmed by life when your only a teenager?
