My sister "Sarah" is a 24 year old, who in the last 2 years has gotten herself into some real bad drugs. Cocaine, pills, and now recently within the last 6 months or so crack/meth. I live with her and my mother. My mother is not the most perfect person, but she has a decent job, loves us and lets us stay here rent free while we go to college. Basically my mom can't kick my sister out of her new dream home she just bought 2 years ago, because my mom is a bit of a pushover and my sister is very manipulative and abusive to her. Even though my sister steals from us, brings random people over at late at night while my mother and I have work in the morning, does hard drugs (my mom and I smoke weed that's it) like crack and stays up for days cleaning.  And as I type this she comes in asking to use my car ( I said no cause she has a suspended license) and yells at me and starts crying cause I said no.

I just want to leave since I cant convince my mother to kick her out, but I only have a part time job and dont have enough money to move out and I'm going back to college in 1 month full time. I still have 2 more years of college until im graduated with my Finance degree, but my head explodes every time I'm near her or hear her voice because she acts like she is 10. At this point in my life I just ignore her because I know she'll start telling me how much of a bad person I am because I won't do something for her.

I have a great relationship with my other sister, mother and 2 brothers. But Sarah seems to be slowly destroying her connection with each of us by how she acts. My sister "Brindi"comes over a lot and is basically Sarah's best friends, but "Brindi" is getting tired of her not growing up and wants to move on with her life, like me. And my brothers are too busy started their own families.  

What can I do to get myself on my own way and away from my sister, Sarah, that I want nothing to do with?
