My Dad died of a heart attack last month and I was there. I tried to help him but nothing I did helped. It was horrible and I keep replaying it all over in my mind. Anybody have experience with this? My Mom past away last November, it was hard because she sufferered so much (cancer) but it was almost a relief. This is so different. I have to take sleeping pills now to sleep and I'm considering taking an anti-depressant.
