I feel this way most of the time. I hope your daughter will find some comfort in counseling. I know my family feels helpless with my health problems and my kids get angry at times also. My husband says he wishes there was a way to take this pain away from me, I know it bothers him a lot as well. I think it's because the way my health is, they see me miserable and they feel helpless as well.
As for comp...I'm in the same boat. I feel lke it's sinking.

Sorry I'm not in the best of moods myself tonight either. The pain is at a high peak.
I do understand, if it helps your not alone.
