I was and still am, pretty sure I have something with ADD/ADHD may it be related to some anxiety issues or the seemingly anxiety is actually the ADHD.
I brought up the subject with my therapist once and I said I'm not sure if that is because I'm moderately anxious all the time or it is the ADHD really.. I haven't been tested for ADHD by doctors or something, ever. so I ask What came first, the chicken or the egg ?

I tried taking Ritalin few times from diagnosed friends with ADHD while in college,
oh boy ~ It was like I took a double dose of MDMA, so later I took smaller dosage of Ritalin and same effect, though less intense but nowhere near treating my attention issues so it is a really dangerous area, and I'm not diagnosed with Bipolar even (cyclothymi0)
