Hi Cindy,
I think I can understand a bit of what your husband is going through. I was away from these boards for awhile because I was getting depressed for not having returned to normal yet. The truth is I know I am doing real well and that I am recovering quickly.
My doctors are even pleased that I have gained back all the weight I lost from the surgery. (I am, of course, waiting for them to realize that at 270lbs gaining back that 30 might not have been a good idea and tellng me to loose weight

) I still plan on trying to go hiking in the Rockies next July.
What has helped me is trying to take a moment and being objective about things. I still have a hard time doing push-ups (which is keeping me from returning to Tae Kwon Do) but I no longer have to nap as much as when I first got home. I still can't sing (which some might think a blessing

) but my parishioners have told me I am speaking very clearly. Perhaps you might be able to gently remind your husband of how far he has come and with him set realistic goals for the short run. Having a longterm goal of "normal" would be good as long as he rocognizes it may be longer than he thinks.
Peace,
Fr. Mike
