Shelz, please don' be so hard on yourself. You maybe overweight, but that does not make you ugly or disgusting. Beauty is not just skin deep, its also what counts in the inside, and from the posts you've posted to me and the others I've read, your BEAUTIFUL! NEVER EVER think you're ugly because your overweight. It is not true.
I personally am classed as being obese. However, weirdly enough I don't see myself as 'fat' as that. I too (like Peachy) try and dress well. I never look at what size I'm wearing as different shops I wear different sizes - I can go from a 16 - 22 depending on where I am!! However, I do make sure that I wear clothes that I feel comfortable in, and in return I look good in them. People don't tend to believe me that I am obese, because I dress well. Clothes that fit properly really do make a difference. No point in trying to fit into something that is simply too small. Also, no point in trying to wear something that is too big, because you can look fatter in that too!
