I agree with all of the above posts. I've been there many times myself as I've recovered, relapsed, then weight restored again. I think the most important part for me was to get rid of my "sick" or too small clothes ASAP. Otherwise, I'd spend half my time trying to fit into them again.
I definitely agree with whoever suggested thrift stores. You'd be surprised what you can find if you take the time to look. Go to a Goodwill or whatever in an affluent part of town, the brands tend to be higher end there and the cost is still the same. I found two Prada purses that somebody just donated at the Goodwill near me and many name brand jeans - Miss me, true religion etc.
Good luck. I think this is one of the hardest part of getting healthy, you've given up or are giving up the unhealthy behaviors, now it's like declaring to the world I'm not sick anymore, even though you may still have a long way to go.
