Bad Roommate?

I've been living outside of my parents' house for a while, and often had good to okay roommates to live in tiny rooms with, but this is the first time that my roommate is treating me like garbage.

Remember that one friendship that I had to break off about a year ago, then made a thread due to her harassing me? My roommate has a very similar personalty to this former friend of mine, so not only do I have to deal with the personality again, I also have to live in the same room with this individual.

Although it's worse, because every time I cry due to depression she yells at me to stop because I'm distracting her, not considering that I'm sad, stressed, hopeless and have depression. Also I get drowsy due to the medicine that I take, so I sleep a lot. My roommate makes fun of me for sleeping for a long time mid day, or even for going to bed early, disregarding me telling her the reason why I sleep a lot every time she says something.

Today, I was venting about my roommate to my significant other, and they said that I should seriously tell an RA about her, because her behavior isn't good for my already weak mental health. My RA told me that there is no place for me to relocate so I'm stuck with her for the rest of the semester... But I feel that I can't live with her, especially since I've been taking naps in the lounge and doing homework in the library. I just don't think this is normal.
