Nothings A Big Deal When It's Not Happening To You

So um... I'm loosing weight. Randomly. And to be honest... It's scaring me. I'm eating a lot. I thought? My mom thinks i'm doing this on PURPOSE. My size zero jeans won't even stay up on their own, & my belt is on it's last hole. Maybe she's blowing this out of porportion... Or maybe not?  I'd never try to loose weight on purpose. That's for girls who don't know who they are. I'm a size zero and in high school, and frankly... I don't care. Beautiful is beautiful. You don't have to be a size a size zero to look like one. You don't have to be a size 5 to feel like one. I was born in a family of woman under 5'3, and men only around 5'8. I was born into a family with woman who have beautiful faces, and curves. I'm not a stick, but i'm not what you can really call... Thick. Loosing weight is the LAST thing I'd want. I hate to stress my mom out over the situation, but i'm really not trying. I guess this can really be dangerous. I guess this is really starting to be a problem. I mean... I''ve been feeling fine, but i've been shedding weight like a bear sheds fur. I just wanna know one thing... If you look at me can you tell? Can you tell that you can wrap your whole hand around my wrist AND have it overlap? Can you tell that my legs are almost the size of your arms? Can you tell? If so, then there's a problem. I need medical help. It's really been stressing me out too. I've been... pretty mean lately. There's so many things going on in my head, and if anyone THINKS they know how i feel then they haven't asked. Because this may seem small, but it's REALLY getting to me. It's irritating to hear about it everyday, and actually have to deal with it. It's annoying to be forced to do things you don'tt want to do, even though it's to "Help" you. I'm tired... I'm SO overwhelmed. There's a couple other things bothering me that just tie into this horrible nightmare, but nothing major. It's just a whole bunch of little problems all tied into one. It sucks.. It's not even something i wanna talk about, cause no one will get it. No one will probably even care. Nothings a big deal when it's not happening to you... and that's how i feel. Well anyways; I guess it's just something i gotta get over, or fix. I'm not sure where to start though.
