i feel for you. i had cancer 2 years ago and my husband had a hard time taking care of me also. and just now i asked him what his advice would be for you and he said, PRAY,,,,if you are a religious man that is the best advice. ask God to give you the strength and also your wife. go and kiss her and tell her that everything will be ok. thank Him also for her and for letting you be her husband, i will l pray for both of you.
