Help!!!

so i’m overweight. no i’m not, i’m obese, i’m 14 and weigh 200 pounds, or so i did. within this last week i’ve dropped almost 20 pounds. yesterday i weighed 190 and today i weigh 181. i don’t look that different though. and my scale isn’t broken because it’s been showing up on three different scales, (that’s all i tried on). i told one of my friends and she said maybe i have anorexia? i don’t really know what that is completely. but i’m never really hungry, but i do eat, i always eat eggs everyday and some snacks. so i’m not sure what’s going on so if someone could help me figure it out that would be great:)
