I think it's natural to go through a mourning period. In fact, I think it's necessary.
It all happens so suddenly, doesn't it? There's no getting used to the idea. On second I was an active, athletic professional, then I opened my eyes and I was some stranger battling profound physical and cognitive challenges. Not much chance to get used to the idea. It was like waking up on an alien planet - minus the probing.
There seems to be stages in the emotional recovery. The first, for me, was denial. I just thought I could will myself back to my old self. Well, that was a disaster.
I think, now, I could be reconciled to my situations if I could just be a more positive presence for the people around me. It bothers me that I can no longer contribute an income to our family. I hate myself for the outbursts of temper.
