Unhealthy People Causing Undue Stress

My roommate is mad at me. Yes, I had a thoughtless moment. But it was fairly minor in the scheme of things, and she chose to essentially cuss me out via text because I hurt her feelings. I apologized, via text, and now she is ignoring me. She doesn't know how to express her feelings in a healthy way, and I am generally the target since she has no other close friends. I am thinking that this lease term will be our last lease term. I'm not doing her any favors by allowing her to have this hold over me, and I feel very much like I'm in an unhealthy place today, since her silent treatment means I can't find peace in my own apartment. Her disproportionate anger over any perceived injustice is exhausting. She needs to get counseling, and I've told her this over and over. She is too busy hiding from reality to get it set up. I'm frustrated and stressed, and frustrated that I am stressed.
