I think everyone must feel that way some days, it's impossible not to if you have a heart. I don't really believe in "god" as the big guy in the sky kinda god, but I do wonder why this happens to people. Some days I think, "we treat our animals better". We keep people alive long after they should be let to go, just because we are medically able to!
That being said, I am very good at what I do. I LOVE the residents because they become my family. Most of them have limited visits from family members, so I am their family, the one they see almost every day, the one who hugs them hello and sits down for a minute to have a little chat. Most of my fellow nurses think I'm nuts to get so close to the residents, but that's how I am and it sounds like that's how you are too.
If I think about it, yes, I get sad for them and feel the loss of dignity etc. But, I can make them smile, and do the little extras that make their day a little better. We can only make their last days more bareable. They are in the siutation they are in and feeling bad won't help. You can empathize and feel their pain, but in the end you are making their last days and years as good as they can be. Keep them comfortable, give a little love and move on. Yes it's really really hard, some days worse than others. But someone has to do it, and it should be someone with feelings. Hang in there. Or if you really can't, go. best wishes,
