I am 13 and am stating to woder about my weight I feel like I'm fat when everyone tells me I'm not I am 110 pounds but tall and thoughts have been coming to my mind about dieting and vomiting to get rid of the pounds I have been skipping meal s and lying to my parents just so can go to the gym to work of the extra choclate bar I had today. I don't know if I'm killing myself but I'm doing this all for the appearens for a guy. Is that wrong?:confused:

Yes. You are hurting your body and messing up your head. Stop.

Yes, doing this is going to harm your body and keep you from having that healthly glow. Please check out this eating behavior test; this website has a lot of good additional information as well.

I believe you are going through anorexia. You see yourself fat, but others do not. I recommend seeing a doctor, he/she will be able to help you. Also doing anything to your body when your hurting yourself is wrong.

I see you mentioned that you are doing this for a guy STOP, if the guy doesn't like you for who you are then is he really worth it... think about it to yourself what are you doing to yourself, and is it really worth it long term...
