Matt,When you are anerexic your matabolism slows down so when you eat anything you gane it all back its very true!! I can not believe you dont know the dangers of anerexia im 12 and i know. Its very seriouse and it happens through time like lindsey says its a mental disorder! and you dont wake up one day and say i want to be anerexic its a process that you rarelly live from if it wasnt a mental disorder dont you think people would start eating again once they found out they were probly going to die!! just think you in a mental instutution!!
