My sis has ADHD, my cousin and I have ASD. My other cousin is NT. We suspect my 3rd cousin had ASD also but she died young do no diagnosis.
We are all “high functioning” in that we have jobs, homes, relationships, etc..
My niece has ASD, ADHD, Tourette’s and other issues. My nephew has ADHD. My DD seems reasonably normal but is dyslexic like her Dad. My normal cousins kid is normal. My ASD cousin has no kids.
We assume my dad has ADHD but he has no formal diagnosis.
Basically we are a family of oddities. We live with our various issues and have found happy lives. I’m divorced but my new boyfriend is lovely and he is odd too (ADHD I think!)
