My heart goes out to you. I am watching it play out in my family. Remember your wife is going through changes from who she was to who she is now. It is hard to watch or even deal with at times. Being unable to do things she used to take for granted is stressful on her and with the reprogramming, no matter how slight or large, she is making adjustments. Your dressing is probably not too high on her issues chart. Go ahead and vent, we all are pretty good listeners.
