I have a sixteen year old (ADHD). Medication has done wonders for his focus and grades. But he often does odd things publicly (at school) which I believe truly affect how he is received (has no friends). He isn't doing anything wrong (for example: doing sit-ups by himself, during lunch time). But he doesn't understand that it draws attention to himself in an awkward way; and kids his age don't want to hang out with someone who may embarrass them. Am I the only one experiencing these concerns? How can I help him curb the awkward behavior?
