Vern, that's an awful thing to happen. My mother is a retired Trauma Nurse and Paramedic. After seeing too many of them, she made me swear never to do that. I never did, although that may have something to do with her saying something about knowing how to 'cause great pain and suffering without leaving those pesky bruises for evidence...'
You'll find your way back to your happy place and then the good memories will come.
