It really opened my eyes to what AD(H)D is really like from someone actually suffering from it and speaking his mind without mincing words, and how hyperactivity is sometimes overemphasized in the diagnosis. So some people get the impression that if you're not hyper it doesn't apply.
And for me specifically this was so ironic because ADHD was the one disorder that my parents insisted I never had, so I just ended up believing them the entire time I was with them.

And it certainly has something to do with anxiety.
I might have had panic attacks at one point when the pain was new and I wasn't sure if I was in immediate danger. Even after I sort of got used to it and it became "normal," it still stresses me out but not in an "am I going to die in 5 minutes" sense, spurred on by late-night WebMD binging.
