I will add that Kevin was very depressed at the point you are at. He was very frustrated and kind of hard to live with for awhile. We avoided invites to dinners. It was strange that our friends even invited us for dinner and couldn't understand why we wouldn't come. I had to privately explain that it was quite hard for Kevin to go places and watch everyone eat.
The one issue we have now is that he can't taste ice cream and it was a favorite. The kids always want to stop for an ice cream and he gets really mad! We wait until he goes back to Alaska for his 3 week hitch to get ice cream!!
What you are feeling is normal. Be good to yourself and know you will get past it.
