One thing that I consistently notice about young posters who come here wanting to breathe free. They have a tremendous amount of respect for, and think it carries a tremendous amount of weight that they "make good/excellent/superior grades" or "am in college prep classes" As you mature and get further away from high school world, or even from college, you discover that being a good student isn't the same exciting promise filled credential in real life that it is in school settings. To be blunt, no one cares. It isn't important.
Also, be careful about throwing around the "my parents are Sooooo abusive" card. If this were true, this had been determined and you were dealing with the social services networks, you would be in foster care. If your mother is truly an abusive parent who doesn't care about you, she won't pursue you when you move out legally. Your crisis interventionist/school counselor type person who is actively involved in this situation should be able to answer the question about school records for you, it would seem.
Don't tell adults you have "raised yourself" until you have been out there taking care of yourself for a few years. You'll eventually come to the realization that getting back and forth to school and work on your own does not mean you're independent. You grew up this close to majority with a roof of some sort over your head and transportation provided, probably from a home with utilities and running water and cable service, some amount of food and clothing provided. "Being on my own" is not something you've done since you were old enough to walk and talk.
