I need some answers regarding emancipation?

I'm a 15 year old girl in Virginia. I know I need to wait until I'm 16 before I can get emancipated. I know I need a means to support myself and I need to be living on my own. When I'm 16 (more likely 17) and I have a good enough job to support myself, I'll want to find a place to live and things of that nature. I've seen some answers on here saying that if someone gets emancipated, he/she CAN live with a roommate, and others that say he/she CAN'T. I have money set aside that was won in a legal case, it's nearly $30,000, but it is in a trust fund which I can't access until I'm 18. If I could access it, it would help with all of the expenses, but I'm not sure if anything could be worked out about it. Also, due to my mom's controlling nature, she wouldn't LET me move out. More than just not letting me move out, she creates other problems for me because she is controlling. For example, she refuses to take me to a clinic or anything to get evaluated for depression. I know I have depression problems, and they are seriously affecting my grades at this point. She doesn't let me out of the house other than for school, so there's not really a possibility of going by myself. She is sometimes abusive, though she stopped being physically abusive after I started to block her attempts at hitting me. However, I'm not sure that anything could be proven, other than that my grades have gone from being A's and B's all my life to D's and E's now. I understand what needs to happen, but I'm not too sure how to go about getting it all to work.

so my questions are:

Is it possible to be emancipated if I'm living away from my parents but with a roommate?

Is there any way to get money from the trust fund? (maybe something that says I can access it if no longer under the jurisdiction of my parents?)

What can be done if my mom won't let me move out, if I can prove there are legitimate reasons that it would be in my best interests? Could I just leave anyway?

Is there a way I could get free legal advice?

Any help is appreciated, thank you! :)
