3 Fat Chicks on a Diet Weight Loss Community

Hi everyone! I've been reading most of your posts and I finally got the courage to register, lol. Let's see....I'm 19 and I currently weigh 165lbs. I want to lose another 40 lbs as I am 5'6" and growing up, I've always been very slender. I know I'm not "fat" or anything but it gets me so depressed when I think about how much weight I've put on during the past 2 years. What's worse is that I don't even fit in the same jeans I wore 6 months ago! :( ...
Since I've been reading all of your success stories...it's giving me courage to lose the weight that I feel has been holding me down. I mean if there's incredible people on here that can lose 110lbs...then why am I having such a hard time losing 40?..it's beyond me haha
