When I was younger my mother was in and out of the hospital. I couldn't stand to go see her there, but I was her "nurse" when she was at home. My father often forced me to go anyway. Eventually I learned to seperate myself from, well myself I guess. This allowed me to go without the panic, fear, and guilt that otherwised plagued me. My mother was mostly in no danger of dying, but she looked awful, and it was...well scary to a young child.
I also had an older friend who was dying, they had her in a nursing home...towards the end I refused to go, I could no longer stand to see her tiny frame twisted underneath the covers (she had rheumetoid arthritis), I didn't want her to see me cry...so I simply did not see her. I still feel the guilt of that decision.
Some people can put their selfish interest behind themselves and are able to help those who aren't...pleasant to be around, those are our wonderful doctors and especially nurses. And then some people cannot, that is their weakness, but they have other strengths.
If you can you should try to help her, you can see a shrink about it yourself. And if you can't help, it is no shame for you, that just was not one of your strengths.
