What should I do about my room mate threatening my belongings, personal space, bullying me, and stalking me?

Asked in Murfreesboro, TN - 8 months

Here the past 3 to 4 months have been a living nightmare. She has been stalking me on Facebook as well as referring my person in a bad manner without cause. I feel secluded to my room because I can't even go two steps without her approaching me about something. Both of our names are on the lease. She has come in and out of my room on multiple counts without my permission, and has even bothered me while I am trying to sleep by means of slapping. She bullied me into giving her money for bills that I didn't have. It has left me in situations before where I wasn't able to eat or get around for days. She has threatened to get rid of my personal belongings, and telling me to not expect my things to be there when I get home one night. I have kept my mouth shut, but I can't any longer. Help?
