Thanks for the advice everyone! I really appreciate it!

I thought I'd give a bit of an update for those who are interested.. I have let it go for now, like some of you have suggested, but some plans have been discussed. First let me say that My grades were bad freshman year, then went up to not so great sophomore and junior year, so I need to go to community college to raise my gpa (and get in-state tuition), then transfer to the school I want... I recently mentioned to my mom that I was looking into community colleges in California, near where I want to go to school, and she said she'd have me live with my grandmother (my dad's mom), and that she'd even be willing to go down there and help me clean up and set up my aunt's old room if my grandma said I could live there (which we knew she would.. she used to always tell my mom to send me to her for at least a summer). Anyway, my mom even said something about being willing to pay for everything but gas! I talked to my grandma either later that day, or sometime the next day, and she said I can live there!! I'm one big step closer to what I wanted advice on, considering that not only was my mom against me wanting to join a sorority, but she used to tell me that she wanted me at the local community college (30 minutes from our house) and would get upset when I said I didn't want to go there..
