My friend/roommate went through my mental health meds and is telling everyone?

TW: mental health concerns

My roommate confronted me while we were drunk the other day. She told me she went into my room "by accident while looking for me" and "accidentally" came upon my anxiety/depression medication. She said that because she's studying psychology at college, she knows what's wrong with me and told me that she always thought my life was perfect before looking through my room and finding this. She then pried into my life and I felt compelled to tell her some really private things even though I didn't feel comfortable.

Now I've found out that she told her boyfriend and some others that I have depression and that I might harm or k*ll myself. She keeps insisting that she's worried about me. This is not true about me and I never told her such things. I went away over the winter break like everyone else and took longer to come back to take care of my mental health. When I came back I was welcomed by other people but she said in front of everyone "I thought you were dead." What should I do? Her insistence actually has the adverse affect that she claims she wants to have; it makes my mental health worse.

She still continues to act weird, like she is my mentor or something. E. g., the other day I asked her to borrow scissors for my work, and she replied "what do you want to use them for?"

Should I confront her? I don't want a huge drama. I don't know if she's doing this to be weird or is trying to be a friend and just comes off wrong.
