I've been diagnosed with both

If you use reddit, there's a subreddit there, I think it's r/AutisticwithADHD or something. I also have an ADHD diagnosis but no ASD diagnosis, and that helped me.

They are*very* commonly comorbid (occur at the same time) so it definitely wouldn't be surprising! It would be worth looking into symptoms and seeing how they align with yours, and trying coping skills for autism specifically

It's insanely common to have both and they have a lot of similar symptoms and coping mechanisms/treatments. I would suggest looking into a number of creditable sources for symptom differences and comparing how your symptoms add up. But because of the similarities in experiences even if you don't have both its fully understandable to relate to both

ADHD and autism have a lot of overlapping symptoms and are comorbid with each other, and you could well have both. I certainly do
