Hello.. Just started yesterday

I'm a 37 year old mother of 2 . My goal is to be fit by the time I'm 40. Acording to this site, I am at a healthy weight at 140 lbs (I'm 5'5") , but since I was always pretty thin , it feels fat to me. I want to be back around the 120-125 lb range, and be lean again. I want to be able to see my hip bones again, lol, and feel good in a bikini this summer. I'm in a size 9 jeans now, and want to be back in either a 7 or a 5. Since I have a small frame, it is possible for me to be that thin and still be healthy. That is the size I was before having my son 8 years ago. I feel if I dont do something to control my weight now, I will just get bigger, and I dont want that. I am carrying the weight in my stomach and butt. Looks kind of funnt to me when the rest of me is still thin, and then I have a stomach and a big butt.. so I am working to build my skinny top, and lose on the bottom half.
