I always used to be really skinny but now im steadily gaining weight and its freaking me out?

You gain weight when you get older. This is not necessarily bad. You get more of a womanly figure. You may have noticed your getting bigger as well as your hips. You know how those celebrities you see have great bodies. Did you ever see pictures of them when they were in high school? They don't look the same, do they? A woman is at her loveliest in her 20's and early 30's. But it is a good idea to eat healthy and exercise. Good Luck.
