How Can a Foster Child Get Out of a Guardian's House

My question involves juvenile law in the State of: Pennsylvania.

I am looking to get out of my legal guardians house. I am 14 years old, soon to be 15, and feel as if I am not treated correctly. I also feel I am ready to move out and rely on myself. I am in the process of getting my working papers from my school, and looking for a reliable job. I do know that this will be hard, because of my age, but I am eager to try to get away from my legal guardian.
I am a foster child to my Aunt. And She will not allow me go back to my mother, which it is a private matter. There is not child services involved. I feel that I am being mentally abused. She has sat there and told me I am not going to have a future, and that I will not go anywhere in life. But this is not true, I have plan, and goals in my life, which I am already trying very hard to reach. She makes me clean the house a lot, which I don't mind because I like cleanness. But she sits home all day, not implored. But she does get a check for having me, from the state. Her long term boyfriend and I do not get along at all. He is very mean, an ex drug addict, and simply does not know how to talk to children. I feel as if I am being mentally abused by him too. While he talks to me like this my aunt will not say a word. She will not stand u for me, and doesn't say anything to him... Also I feel my aunt can not support me properly. Her child eat the food in the fridge. If I am not home for dinner, they don't save me any thing. I basically fend for myself in my house. aren't guardians suppose to fend for me?
After I get my working papers from school, and a steady job what can I do to get emancipated or simply away from them? There is no family for me to move into with. My grandmother lives poor, with my uncle and his child living with her. My mom, even though I tried to live with her, I can't.. Not only because the fact that my Aunt would not let me. But because my mother and I do not get along at all, plus she is a recovering drug addict who still has many slip ups. I do know know my father or any of his family either. Foster care is not an option I am willing to do.
Would an option be able to move into an apartment with my long term boyfriend? He is old enough for a house, and had a job for over 3 years at the same place. Could it be possible in some way to go to court, and be able to move in with him? I would still go to school, because one of my goals is to finish school.

I just need to get away from all these people. I am mentally abused to the point where they make me feel like I am never going to be good enough for them. I'm tired of crying because of family,the people who are suppose to love me, and believe in me.

I hate to put it so bluntly, but you have no hope in Hades of being emancipated (and not just because PA has no statute allowing for the emancipation of a minor). And the only way you'll be moving out will be with permission from your guardians.

You're 14. No court in the land is going to let you move in with your boyfriend. He better watch himself, too.

Here is reality 101.

My children think they are mentally abused also. I hear about it every time my daughter is home from the college I am paying for her to attend and I become upset with her actions. Talk to a counselor at school if you think you are being abused. They are a mandatory reporter, if you really are.

There is only one state that will even consider emancipating a 14 year old; that state is NOT Pennsylvania, and even in that state you not only need the permission of your parent or guardian, but that full time job you have while still going to school had better be working as an extra in the Harry Potter movies.

At 14, if you moved into your boyfriend's place on Monday, by Tuesday he would be in jail.
