I like wyllen's advice. I think if you just continue with at least a weekly hop on to the scale and make a deal with yourself that if you GAIN, then you start counting again (at least for a week) to get your control back on the portion size.
Maybe you're expecting too much on the clothing side too...were your clothes at your high weight tight? Maybe you're just getting comfortable in the wardrobe you have. You know, I think we all learn over time (whenever we get more weight than we should) that there are some brands that are bigger but still have the "right" size on the label, right?
I'm thinking that maybe you should take a little jaunt to the department store and have some fun just trying on stuff. You might find that even if your SIZE is the same, that the RANGE and types of clothes in that size that fit you (and maybe flatter you???) are different now. If you can afford it, perhaps this is the time to think about treating yourself to a new outfit if you find something fun and funky, (or sexy) that you like to help you get some of those positive feelings back. And even if you don't buy anything, maybe just the fun of trying some new stuff on will help you think differently.
You're doing great!
