I cant help you there, i am about as antisocial adhd as they come....

i would rather putz around on the farm working on stuff than be social....
are you/your family a part of any homeschool groups, or are you in/interested in 4h? My mom was one of the leaders of a homeschool group on the southside of chicago while i was still homeschooled, we had monthy meetings with stuff that interested the kids in the group, and we had a weekly bowling club that was organized thru the group, (only reason i tolerated that social activity was because i liked to, and was good at bowling with a 195 average and 267 all time high score

)
What are your interests, are there any sort of after school clubs you could join anywhere?
