Americans seem to be very quick to diagnose people and assume things. I am going to be very honest here, This is absolutely appalling and could be considered bullying, accusing someone for being on drugs when they are not using is defamation of character and could affect her chances of being accepted in to university one day. No wonder the poor girl is depressed!! Jesus Christ. She has depression which is totally normal and common in teenagers, all she needs is some medication and counselling.
