text: i think my little brother is going anorexic, can anyone help? my little brother has started eating way less and exercising way more, it seems that he is going anorexic but some people just laugh because it is considered to be a teenage girl disorder, please help! tell your parents. if they won't take you seriously, try grandparents, other family members, his or your teacher, just anyone who can talk to your parents and your brother. your brother may need treatment, so the sooner he can get to a dovtor the better. you're a good sibling, looking out for him! your brother will appreciate that when he gets older.
