Emancipation: Can I Legally Emancipate?

I just turned 17 this month and I am very intrested in becoming emancipated. I am currently taking the summer off from the local junior college to find work. I have been running away from home off and on since I was 14 years old. I have been arrested as a missing person and by the ABC unit. I have been arrested twice but never charged. I did not graduate high school. I have been a truant for many years. I am scheduled to take my California Proficency Exam next month. I am looking to share an apartment with my
19 yr old boyfriend of one year. He has had a job for quite some time, but also never graduated. I have an interview for financial aid at the college I attend and a job interview. I am trying.
My reasons for leaving is my unstable home enviorment. There is nothing I would consider abuse.
I have 2 half brothers and a half sister. My mother has seperated from my step father for 3 years and refuses to give him a devorce. The youngest (1 yr old) is a "love child" if you will. My mom had me at 15 and assumes I should have the same amount of responsibility she had. I am CONSTANTLY watching her children (9, 4, and 1) and rarely am I allowed to leave my house. She allows me to to have boys spend the night and get high and do all those things youre not supposed to at home or at all, but then she plays mind games with it and grounds you.
For the most part I lived alone in my house when I was 14, except for my crackheaded pervert uncle, until my mom had the kids back when I was 15. She was too busy being single after an abusive relationship with my stepdad. She came home drunk more times than I did. And didn't come most of the time. I am sober now, after a rocky couple years and I really think I deserve the opportunity to earn more than what I have been given.
I didn't fully live with my mother until I was 9 when my grandmother died. I do not feel that I have the emotional bond between mother and daughter people talk about.
When I am grounded I am not allowed to go to school. I failed high school miserably. I have no support. I am not allowed to get a job. My mom is never home and I sit here with her kids. We have had several run ins with CPS, though I doubt they are on record. I don't know my dad, he isnt an option.
I swear she is crazy, I don't know how to put my story into words. But if you saw what goes on, you'd say what everyone does, "Stand Up For Yourself!"
I really don't want my siblings taken from the household. And I don't want my mom in trouble. They weren't around to see her at her worst. It's only me that needs help. She thinks I owe her the world, because she had me at 15. I ruined her life. And I would like for her to take responsibilty for her life and children.
