I want to move out too, and I am adopted.. I will lose mt medical card and possibly college funds... What should I do? At my house I am constantly being put down and being bullied by my younger siblings and threatened by them. I can not stand living there and my mother doesn't help. I need advice from everyone.

As an adult you are responsible for your choices, You are free to move out but your parents are also under no obligation to pay for your follies either... if you stay or not.

It is your choice, and life is hard, living in a rooming house with buds and drunks making noise at night down the hall is hard too.
Having to work hard doing manual labor since you did not go to college being dirty and sore all the time,

It is your choices, you will have people on you, either at home or at work or in life all the time.

Are your siblings adopted too?
