Am I underweight? Is my eating pattern unhealthy?

Alice in Wonderland · Yahoo User

I am a young teenager, 5'3" or so, and I currently weigh 89.8 pounds. I've recently been put on ADHD medication. The medication makes my hunger go down. So usally when I take my medicine before school, I'm not hungry during lunch. So I eat about 5 grapes and I'm done eating. My mother had started noticing that I had lost some weight. She would ask me everyday if I ate my lunch, and I'd lie and say I did. She'd text me on what the 'teria was serving when I got home. So I had taped it up in my locker so I would be able to pass without being yelled at for not eating. In a month I had went from 108 pounds, to 100. My grandmother came to vist us for Thanksgiving, and she kept talking about how skinny I was and she seemed quite worried about me. My mother had tried to take me off my medicine because of my weight loss. She figured that if I was off the medicine I'd gain back some pounds. But I didn't. I still didn't eat. I was hungry, but I liked my weight. [read below for the rest]So I didn't gain any weight. My mom became very upset about the whole thing. She finally asked me to show her what my stomach looked like. So I did. She kept telling me that I was too thin.Now, all my friends think I'm anorexic. And honestly, I'm scared they're right. My mom has backed up about the whole thing. She assumes I'm eating lunch, but I'm not. If I do happen to be Anorexic, then what should I do about it? But I mostly want to know if what I'm eating too unhealthy for a 13 year old, and if I am underweight.
