Hi, my 13yr old son has no real friends. It's heartbreaking, especially in the summer holidays. He's lonely. Won't join clubs and no interest in anything other than YouTube. He has ADHD and gets overexcited so when he does find someone to hang out with, he acts silly and wants to play. I think he has a reputation for being a bit embarrassing to be seen with. Really tough situation. Grateful for any advice.
