To JW,
Hopefully you are doing better after posting your letter. I am the caregiver for my husband of 38 years. We, too, do everything together and travel when we can. His treatment hasn't caused him the problems your wife is experiencing, but there are times when he just doesn't feel up to doing anything. We did spend last week in Gatlinburg with our son, daughter-in-law, and grandsons. He kept on the go and was tired when we returned home, but he did enjoy the time away from home. Keep encouraging your wife to be up and about. It's normal for you to feel depressed, but talk with your family physician about it and get help before it gets too bad. I am on Lexapro for depression, and it has helped. There are times when you just have to get help, now may be the time for you. You need to be strong and upbeat for her. When you feel down, don't let her know. Get away by yourself (the park is good), walk, vent your frustrations outloud, and do whatever you need to do to clear your mind and return to her care. If your spirits are good, hers will be, too. Good luck to you both.
Jenny
