Another Question about Loseing Weight...?

Ok so Last year I was around 120 lbs ( im also 5'7.. So im tall) But anyways I starved the hell out of myself, hence getting down to 120. Well I started eating and everything is better now. Unfortunately I weigh 157 now. And I hate it. I love the sweets. And I also cant seem to be full enough. For instance, yesterday I ate 2 PB & J sandwiches a baggie of chips, a necterine, banana, one orange soda, 2 cups of coffee and for dinner I had a vegie burrito. I hate eating so much but because I started eating again my stomach is bigger.. What kind of foods will keep me stuffed but also (somehwhat) taste good. Im now exercising everyday. I just cant get full enough. I want to fit in my size 7s again. I know thats huge to most of you but I have never been in a size 7. And thats a triumph for me. Any help would be greatly appreciated. Im motivated and determined. I just need some help along the way. -Steph
