Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. For anorexia, We approach with different strategies. Every strategy depends on the behavioral aspect of the client. In this case, you can tell your son that he is fat. Agree to what ever he says and sympathize. Slowly gain his confidence and then you can take him to a psychiatrist for necessary treatment. Anorexia needs psychiatric intervention and then in the later stages psychotherapy and life style changes. Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition. Hope this answers your query. Available for further clarifications. Good luck.
