To make it short: my friend learned about two months ago, that she is very ill. It's not life-threatening, but serious nevertheless. She performs worse at work, she's weak and scared. 

Me and her other friends tried to do our best to keep her company and to help her in any way she needs, but she is one of those people who hate being dependent. Plus with all the fear and trouble at work, it gets really tense most of the time.

For two weeks or so, every time she opens her mouth, it's to say something hurtful to us, even (or especially) when she has no reason to. And every time when somebody tries to calm her down, she uses the illness as an excuse and it ends up more or less with a "fuck you guys, nobody asked you to hang out with me, if you don't like it then you're most welcomed to leave me all by myself in this empty apartment".

She wants attention, but she's stressed and she snaps at us. I personally cannot really handle it anymore and fortunately I don't see her every day lately, but I'm only checking on our mutual friends to make sure if she's okay, because I cannot bare to say "hi" and be accused of something again.

So, my question is, where should I set boundaries here? How tolerant should I be? Am I being a bitch for trying to shield myself from this? I know that she's just scared and I would love to help her, but she makes it so difficult. :( Right now I feel really guilty for even asking this, but she's borderline emotionally abusive.

Friend found out she's ill. She's clearly scared and takes it all out on her friends (including me). It's very emotionally draining and I find myself getting more and more afraid of contacting her even though I feel like she needs my support. What

My friend is very ill, she's very scared in the face of the possibility of dying and it's really stressful for her and our other friends. She has little patience and it gets really bad when she is angry.
