In the back of my mind this still makes me mad

I'm sorry this is a little long

So my favorite cousin, Jill, just called me. She was at the hospital with her husband for testing. Maybe cancer they don't know. Anyway, she calls and is not happy about the fact that she stayed at the hospital all day yesterday. And half a day today. It's not that she doesn't want to be there for her husband. So I'm listening and as she's complaining I say, yeah I did that with Dad more times than I can count. She doesn't acknowledge I said anything and continues to talk. I love her and I feel sorry to a point. But she, her 5 siblings , or my aunt and uncle ever cared that for a year I was at the hospital with dad more than I was home. The last four months he traveled from hospital to nursing homes where he eventually died. Not her nor her family ever asked how I was doing. They never offered to help in any way. Plus they never visited Dad.
So I'm still hung up on this fact and I can't bring myself to fee too sorry for her.
