If it causes you problems, you should use whatever means available to you to end the interference, shouldn't you? For some, it's mindfulness. For some, it's medication. For some, it's exercise. Unless you're a doctor well-versed in medical disorders, you can't evaluate if medication would help. You can try mindfulness exercises and physical exercise routines, and if it doesn't stop the feeling that something about the way your mind works causes problems, why not see a doctor?
You have the time (doesn't feel that way, with all those DUE RIGHT NOW tasks I have that are way more important) to make the appointment (and why can't they just see me today, it probably won't take that long, it's just a questionnaire, right?), drive to the doctor (and deal with all those idiots on the road who clearly can't drive as well as I can, and where did they learn the rules of the road anyway?), wait in the waiting room (didn't I just fill out all this paperwork online like they asked, trying to be efficient? Why am I doing this again? I should tell them there are better ways of doing this! And that guy coughing over there, didn't he learn to cover his mouth? Ugh, figures, reading a trash magazine, probably doesn't know any better) and talk to the doctor (who I should totally tell about the nootropics I've been reading about to see if he knows about them too and can just give me some of those and send me on my way because I've got shit to do, and it ain't gonna do itself, and OH LOOK, THAT SQUIRREL JUST JUMPED TWO FEET IN THE AIR!). It can't hurt.
Note to the reader: the parentheses indicate my own thoughts when I did this years ago. I was told later by others I've met with AD/HD that they had the same exact thoughts, and it helped them to see a doctor. I was also told by others who didn't have AD/HD that I needed to grow up, suck it up, and just do it. To me, that clarifies the difference of someone with AD/HD and someone without. Either you can identify with every single one of those things in parentheses, or you think, "of course we all think some of those things, but we put our big boy pants on and get it done; it doesn't mean you have a deficiency in your neurochemistry, it just means you have to motivate yourself a bit more to get anything done."
