Attitude, attitude, attitude. I know it's not easy but remember, Jim, that Deb is your lifeline and Deb, remember that Jim is going to have good and bad days. Neither one of you should take anything personally. You both are suffering but I bet you both are strong and you will get through it together. Keep as positive as you can and this too shall pass!
Best to both of you in fighting the good fight. There are better days on the other side.
