What should I do?

I overheard my roommate bitching about me today on the phone to her mom. She was right outside our dorm door and talked loudly, and so I could hear her quite clearly.

She basically hates me guts (although couldn’t say how I annoyed her) but just that she hates me, I’m stupid, I’m annoying, I’m fat, and she doesn’t want a roommate. Oh, and she spilled secrets about me.

I’m EXTREMELY hurt. I’ve spent time with this girl and we’ve talked. I considered her one of my few friends at college. I thought she liked me because we both opened up to each other. I’ve been very accommodating to her (she is very picky/social anxiety/elitist, and most of the time, I’m not even around, I’m at the library. I respected her need for privacy and left when she was going to be camming with her bf. I never played loud music, had friends over, or used her stuff without asking. I’m just so upset because I trusted her and thought her to be my friend and now I feel betrayed.

Room draw is coming up. She basically had LIED to me before saying that she “wants to be roommates again next year”. Now this happened! We need to decide what to do. I don’t want to room with her again, as she has hurt me and has proven herself to me to be a lying tart. NO way I could trust her again.

I’m not so much angry…just more bitter and sad. I’m disappointed.

I will need to tell her soon not to plan to room with me, just so she knows. She has no idea that I overheard her and how hurt and sad I am. Should I just tell her not to expect a room with me again, or should I tell her that I overheard her conversation?

I have no idea.
