Hey, I read your post and decided to register so I could reply. Let me tell you: I know EXACTLY how you feel. Definitely. I'm 5'3" and weigh 211 (joined WW this past Saturday, so that's a pretty recent number, haha). Really, I think you've hit the nail on the head there. And that's a good sign! Once you recognize exactly what it is that's keeping you from losing weight (in this case an insecurity in your "new" skin), you can address it and make changes psychologically to change your perceptions.
I'll tell a story to give myself some credibility.

When I was in high school, my family had a very VERY bad run for four years. Pretty much someone died just about once a month. It was terrible. And for a developing young woman who lost the most important stages of her formative years, it was traumatic. I had to stop acting like a 16-year-old and act like a 40-year-old. I started to gain weight as a sort of emotional cushion (teenage friends will pester anorexics; they don't tend to pester overweight pals). I got to college, never developed any sort of real good eating habits, and formed a role for myself: the fat friend. I also tried losing weight (mostly at my mother's frantic urging because of health related issues in the family), but whenever I got smaller (once I even dropped from 175 to 126), I felt so wretched. Guys noticed. Girls noticed. And almost everyone was saying things like, "You look so good now!"
What I came to realize was that I was putting a whole heck of a lot of stock in what other people thought about my body and its shape. I also came to realize that people are always going to talk, no matter what size I am. I could be immobile, stuck in the house because I weigh 5,000 pounds, and people will whisper and say things, "Oh god...can you believe she's so big??" etc. etc. I could be a good average weight and people will treat me differently (maybe smile at me more, invite me places more). Or I could be waifish and people will talk, "Can you believe how small she is?? I bet she purges!"
The trick that I'm trying to master is this: paying attention the only voice that matters--MINE. When I got to the point of not being able to look at myself in the mirror nude, that was a problem to me. I hate(d) myself. Most literally. Suddenly, it didn't matter what stupid things people were saying to/about me. It became very important that whatever I listened to needed come from me, from my heart, as cheesy as it may sound.
I have a really great personal image that I keep safe in my mind; it acts as a sort of "here's the size I'd like to be" picture. It goes beyond the size itself and enters into how I feel, what kinds of different things I could do, and whether or not I can stand to look at myself in the mirror. That's the goal I want to achieve.
Keep in mind that people are always going to talk, no matter what size you are. They may say amazingly cruel or kind things. But what needs to matter the absolute most to you is your health above all else (how well you can live your life, etc.), and how happy you feel in your own skin regardless of its size.
I'm sorry that I don't have any books or anything to suggest to you. Though I might suggest Dr. Phil's stuff on weight loss. You may not necessarily want to follow his program (different programs work for different people), but I really think he has brilliant things to say, espeically when it comes to how people see themselves.
Please remember to take care of yourself and be patient. It takes some time to dissolve fears, especially ones so deeply rooted.
(wow...sorry this was so long...it's just such an important topic!
