My 9 year old son is having a very difficult time losing. Whether it is losing playing a video game, losing in gym, losing in baseball- he can not contain himself. He has been crying since he began playing sports at 4 years old. We thought he would outgrow it as he developed emotionally. But now- he is very aware of his behavior and that he doesn't want to cry. He says he just wants to be "normal". It now has escalated to that he put teeth marks into his arms to stop, run head first into the side of the gym to stop the frustation... It is affecting him at school now too. My husband and I are at a loss. We talk to him and tell him that it doesn't matter if he wins or loses that as long as he had fun and did his best that's all that matters. He understands it when he is not in the moment. But when he is in the middle of playing a game, his emotions win. I'm sure it is effecting his peers perception of him and we don't want him to be scorned amongst the other kids. Please help.
