Hi Sue
I understand were you are coming from but it will do you good to have a bit of me time,feeling guilty about it is natural.
I am very much the same I spend a lot of time in the hospital with slim,it takes me 1hr to get there,buy the time I get back my day is finished,buti am aware I will have to pace myself as I will not be. Much good to him when he comes out.
You will just have to fell yourself he is in the next best place to be looked after,and plan to see a good friend for coffee next time.
Sue you have every right to feel sorry for yourself,I would recommend a good bottle of wine,but it comes at a price a bad head in the morning. Love Eve
