SOCIAL DIFFICULTIES AND BEHAVIOURS

HELLO. I am Mum to a 9yr old boy who was diagnosed last year with both ADHD/ASD. Currently my little boy is withdrawn and socially awkward. He barely speaks to other children and has attached himself to another little boy with the same disorder in his class. Although they are great friends, it doesnt help him mix with classmates. He feels alone at times as his friend likes football and he hates any contact sport or personal contact! I have been told he can walk around alone at breaks which is just heartbreaking.

He has just started art therapy in school though I know very little from it. He doesnt share much information. 

I am finding it difficult to get him to engage with us socially at weekends. He refuses to go out and will not even go for short walk. 

Does anyone out there have any suggestions or have been through similar difficulty? 

Would really appreciate the support right now x
