Taking surgery for granted
You have come to the right place. Were you an emotional eater?? Stress can definately take it's toll as well as depression. I am sorry to hear about your father, but is there someone that you can talk to about your loss? a support or grief group? One of the other things is that you get with your support group and talk about these issues as well as your psycologist. Don't take this for granted as I have seen the results. You lost 89 pounds, and that is fantastic, get the help you need to keep you on track. Best of luck and remember God will either strenghen your back, or lighten your load.
Best of Luck
