Do you have a friend - who is disabled...in a wheelchair? If you do...please talk to me.

I have a friend for about a year...she is in her 30s and I don't know what to say. She has 3 small children...her stroke - well, it's a long story. The issue I'm having is that she seems to think everything revolves around her...and I can understand that. Our phone convertsations are mostly about her...I don't mind...it just feels awkward. I wanted to speak with ppl who have other disabled friends...and wanted to understand what it was like for you...like are they ALL "self-centred"...and is it me that's wrong?
