I can certainly have sensory overload, but usually it's mood-related. I also have a bad tendency to repeat things. I've always thought that was anxiety or hypomania/mania related. I have periods when I grind my teeth during the day or pick at my fingers, but not severely. Again, seems to be anxiety or mood-related. I do not have an autism spectrum disorder. Both of my nephews were diagnosed with Aspergers, though.
