My dad is currently 81 and has had COPD for sometime. For the past few years he has gotten increasingly difficult. He has always been a negative, pessimistic type but for some reason he has gotten more volatile depending on the situation. He's one of these people that is never happy about anything, my brother and I still live in the same house with him. And he feels that he can use us as "punching bags" per se whenever he gets angry or etc. And the most recent is he has come down with a bad cold that he is convinced is the COPD when you an obviously hear that its a cold of some kind. And he has been making us miserable over this and repeatedly we asked him if he wanted to go to the hospital since its the weekend and his Dr isn't around. And the continual answer is no. I seriously don't know what he expects from us. And of course he keeps talking about dying. Not sure what to do anymore, or is it time to just "walk away".
