Hello all!

Hey I'm 18, and a senior in highschool. I have to loose 180lbs. To get to my goal weight which is 160lbs. I've been trying to loose weight for such a long time. And I don't understand why I'm fat, I've been in marching band for 6 years now, and that keeps me active. Plus now I'm on a basketball team. I eat under my 2000 calorie goal very often. I don't know why I can't loose the weight. I really wanted to get my goal before senior prom but it is in a couple months and I still have 180lbs to go. I would still love to loose a much weight as I can before it, to fit in the dress of my dreams.
