I want to know whether he needs psychiatric treatment or medical treatment. He's normal all other time. He's happy, he'd joke around, play with younger kids, do every normal. Activity but throughout once-twice a day he all of sudden wants no one around, he wants to be alone, he doesn't want to talk to anyone. Sometimes his mood swings to anger, he gets angry, he'd say all the terrible things and he'd want be alone and doesn't want anyone around. It's sometimes for half n hours, sometimes for the whole night. His mood swings! please kindly help, he's too shy and insecure to personally get to a psychiatrist. Kindly tell me why is he like this?
