i’m still somewhat in denial myself- i keep reading things here and saying “omg, yeah, i totally do that. damnit!” or “so thats not just me? they seriously know how i feel?! yay!” …. and i’m slowly coming around, but it is really hard to get to grips with- especially when you’ve struggled and slipped through the net for so long (i’m 30- aka: ancient 
) and were completely convinced that you were just entirely defective- all be it in a somewhat quirky and sometimes entertaining way.
i read somewhere recently that people who think they have ADD generally don’t. its those of us who are somewhat dubious cos we just thought we were weird and a bit crap, who likely have it. everyone has problems, but most don’t have quite so many that all fit into the same niche, for the same reasons (dopamine system is a smidge lazy and wonky) , or struggle so hard with them, i think.
i think really, when it comes down to it- whether you call it ‘weird, creative and ditzy’ or ADHD, if your wiring is the way it is and your brain chemistry works pretty much the same as mine and the rest of the board here, and a bit differently to 90% or so of the population, thats how it is.
you don’t have to lose you. what you’ve got here is the opportunity to understand you, and some skills and strategies that you can employ to actively decide to improve upon or change the parts of your personality and skills that might cause you problems at the moment.
if you want to try meds, great! whatever happens will wear off when you stop taking them! i’m used to meds, cos i’ve been on antidepressants for depression for 16 years now (i know!) and for the mostpart you still end up being you, just a little altered when on them- with my antidepressants i have enough energy and drive to haul my arse out of bed by lunchtime, i find myself actually laughing and smiling- i’m still me, just the ‘improved’ version who doesn’t wanna off themselves. with straterra (which i take for my recently diagnosed ADD) i’m still me as well, i’m just a me that can focus on thinking just one thing at a time when required, who feels a bit more present in the moment and self-aware, and who doesn’t turn circles quite so much and forget what they’re doing every 5 seconds- a me with a slightly quieter brain- it still works, its just tuned in better, so i deal with about 3 thoughts per second instead of 300, and i can take them in straighter lines when i need to use them, instead of bewilderedly watching them bounce off the walls in my brain all day.
i had an aha moment when i first started meds- when suddenly and randomly one day i realised i wasn’t thinking *anything*- for the first time ever. i’d never ever experienced total radio silence in my head, and it was blissful- just peace and quiet… looking out of the car window, enjoying the sunshine on my face. you might love it too. if not, just stop taking the pills, or try some different ones.
you don’t need to tell anyone just yet- and i wouldn’t until you feel comfortable enough to answer questions if needs be. some people will say “yeah, no shit sherlock?!” cos it was so incredibly obvious to them, and thats awesome, but some won’t entirely understand- cos people don’t always understand things they’ve only learned about from hyped-up inaccurate newspaper articles, and its a hassle to try and deal with that if you don’t *need* to, to begin with, at least, and it might mess with your footings a bit fi you’re not so solid confidence wise.
just take your time with it (as much as any of us can ), relax, and enjoy the ride- see where it takes you!
