Well i guess your wife knows now
I like what Reed said,"don't listen to yourself"
cuz its mostly self defeating and untrue.
I know it doesn't feel like it now but rehab will be really good. You don't have anything to worry about except concentrating on you and getting better. Forget about everything else now. I grantee you in 5 days you will have a whole new outlook. A positive one.
Bring your slippers and a few pics of family
I am envious, you have a supportive wife, good luck guys
