Post Traumatic Communication Is It Possible For Me To Change My Guardian?

Is it possible for me to change my guardian? - post traumatic communication

I am 17 and I want to change my anxiety, so I can leave the state in order to a different school in the requirements of the state. I'm in communication with the school and have kept up with me, but I can not do anything until you are exempt or a tutor who lives in the transition to the state. My parents are divorced and suffering from PTSD as a result of my father and my mother emotionally and sometimes physically (lack of eating ramen alias of the week), I wanted to have the custody goes to the parents of my friends are willing to take me to and my needs. I wondered what it seems possible to change all my treatment because my mother would pack me if I was not online and I havent in a few years ago my father visited ... Please tell me your opinion?
