Have you ever been around someone who, just by talking normally, managed to shove you into overstimulation?

My nephew is like this. He is 20 years old and also ADHD and I don’t know if our ADHD types are just not compatible or what, but having a conversation with him is so so so overwhelming, I can’t do it for more than a few minutes at a time. And I feel bad! Cause it’s my nephew! And I love him! But he talks a trillion miles an hour and interrupts people every other word and talks really really loud and I know he can’t help these things but I legitimately have to spend alone time in my room after interacting with him. And then I watch my parents interact with him and they’re just fine. I’m like. Yeah it’s just me.
