I know how you feel, but not related to weight. For my first two years of college, I had very long, almost waist length hair. I decided to get my hair cut short and donate it to wigs for kids. So, I went from waist length to chin length. I got TONS of comments/compliments. It was flattering at first, but after a while of hearing "it looks sooo good!" I began thinking "did my hair look that bad before?!" and feeling really self-conscious.

I have no advice, sadly. Eventually as people got used to it, the comments stopped. I guess just wait it out.

It comes with the territory...over time you will get used to it. Just laugh it off. As long as you are looking hott and have confidence, you can count on all the stares and men hitting on you right and left. ;)
