I think you are so very brave..my husband passed with cancer 15 years ago ..I was younger then and able to take care of him.. I've been really sick (gut issues.. nothing like what you all are going thru) and I don't know what I would have done if we'd both been so sick at the same time..your wife is so very blessed to have a fine husband who still wants to take care of her..my David wanted to do the same ..and I was not sick..he was an "old school gentleman"..and a fine husband too.. my heart goes out to you .. he became extremely frustrated with himself not being able to take care of me..it is very hard to not get depressed.. your feelings are valid..and I'm praying for you both!! May the peace of God be with you...do the best you can..I know you are!! (no chin up speech from me).. I feel your frustration..God bless you!!
