Thinner

I weighed myself the other day, because I hadn't weighed myself since April. I've always hovered around 120 lbs. but now I'm at 113. So I think something is wrong. I always thought I was underweight because I have pretty fast metabolism, but I shouldn't be losing weight. It's not like I haven't been eating either. My eating habits haven't changed, so I'm not sure what it could be. I think I should go see a doctor soon.

I hope it's not worms.
