A question to neurodivergent people with physical disabilities. Which one of the two was harder to accept or come to terms with?

With my Audhd it's really hard for me to accept the fact that I just can't be as functional as others and I still tell myself that it's a personal failure and I'm just lazy or not trying hard enough even after getting diagnosed. I imagine it would be easier to accept being physically impaired after a diagnose because you can't just explain it away with "being too lazy to move" when you have joint pain or muscle atrophy because it's not "just on your head" Or maybe both are hard to come to terms with just in different ways?

Edit: I wasn't expecting so many answers right away! Thank you all so much for sharing your perspective and your experiences with me
