It's a horrible thing to see and I wouldn't wish it on anyone. The worst part is I when I try to remember her, I keep seeing how she was in her last few hours. Sorry to hear about your dad, it's hard losing a parent. I didn't take it well and we weren't close, we hadn't spoken properly for years. My wife got us talking again about 3 years before she died. That was hard enough i'd hate to think how it would be watching someone close die like that.
