I am 5'5 and 103 lbs which is nearly underweight, or it might be underweight. IDK:confused:. But even though I weight very little for my height, I am still really scared of gaining weight. If I even gain 1 lb, I'll starve myself the whole day and exercise for hours until I'm back to 103 lbs or below that. I've also been losing weight, last week I was 106 lbs. I don't know why, but I still want to lose more weight. I don't like being almost underweight, I want to be underweight. What's wrong with me ? I was reading about anorexia and I have almost all the symptoms:eek: but I'm not sure if I am. Do I need to get help or is this normal for a teenage girl to worry about her weight like this ? :(

You should talk to a professional, particularly if the weight issue has become an obsession with you.
