I also was recently submitted to my insurance. I share some of the same feelings. I can only tell you that I am concentrating on the new me. I have been eating as close as possible to how I will eat months after I have been through surgery. Once or twice a week I indulge in foods/restaurants that I either will not eat again (my choice) or I think will be a real long time before I eat them again.
That being said, I expect that I will still be same me after surgery, recovery, and learning how to cope with the new nutritional and healthy lifestyle I have chosen for me. Same ol' me, just much thinner.
