I understand how you feel lonely, I am starting to feel very isolated with my ds - who has lots of problems.
Crap at sport and very clumsy too, but worse problems are:
really bad minor motor skills - handwriting appalling, eating very messy (also has oral dyspraxia).
He did have speech problems, but these are ok now
social problems - over-reacting (either too excited or too angry or too upset about things), lack of social skills, doesn't understand social rules particularly, stands too close to people, misunderstands expressions, very literal etc etc
very disorganised - will always forget homework, drop things as he walks, loses things etc etc.
We are all finding it all veyr difficult at the moment- I think what was ok when he was 7 and under starts to show much more now. He is starting to get teased at school, and finds it very upsetting.
He does have lots of good points too, but atm his "differences" are causing him alot of anguish.
