Paty - I'm 5'1" and down to a size 1 - Hang in there, it will happen eventually. You just have to keep reminding yourself that you didn't put the weight on overnight & it AIN'T gonna come off overnight either...
If I'm looking at your stats correctly I'm thinking that you want to weigh 97 pounds when you're @ goal... You might want to focus on sizes or body fat percentages - I'm only an inch and a half taller than you and I'm not anywhere close to that number weight wise
I used to think that I wanted to weigh 110 but when my body fat hit 22% and it got hard to find clothes that fit I gave up on the scale
BTW - it took me close to 2 years to get here, had a few physical set backs but in retrospect I can live w/it..... Now, if I could just quit seeing a "fat person" every time I look in the mirror all would be well....
