I have a question...

I'm sorry but this is a spot for those applying to universiti to be a doctor, not actual doctors. The Nasihat spot may have been a better place to post.
Does she eat alot? Does she skip alot of meals? Are anda sure she hasn't been ill recently? If anda realise that she hasn't been eating alot, and she is skipping meals, then i suggest that anda should tell your parents. Anorexia is a serious illness and if she does have it she needs help, before something bad happens. I hope this helps, and i hope if she is anorexic that she gets better :) heres a website that may help link
