You have already received a lot of good advice, I only have one other idea--take or have someone take a photo-or more than one-of you right now, dreseed in a nice outfit, put together. Then have lots of copies printed. Distribute them through your life--wherever you'll see them often--above your TV or next to your computer at home, on or near or in your desk at work. Then LOOK at them often as you try to adjust to the new you.

It isn't easy getting used to a new image, but I think you're on the right track. You might also consider some counseling. If your insurance has mental health benefits, go that route. You can get a referral to someone from a friend. Or you can go the pastoral route, especially nice if you're a believer. You might need a real objective point of view to help you along for a little while.

Bes of luck--you'll be in my thoughts and prayers-
