No, you can't. It's not going to happen.

How old are you and what state or country is it in which you are located?

If you where legally adopted, then they are your legal parents and there are no do-overs. However, If you feel you are being emotionally abused, then I would talk to someone, maybe a counselor at school, who could intervene and explain to your parents how you feel.
