> I have ADHD. I think. Pretty sure.
I take your hedging to mean you are probably self diagnosing. It's worth talking to a doctor and getting the ball rolling on a formal diagnosis. ADHD is not the only diagnosis with those symptoms. For instance bipolar and autism spectrum disorder. Again, not a doctor, take that with a grain of salt.
There are probably new tactics you can adopt in this thread, and they may help and are worth trying. Advice which is actionable today is valuable. But if this is severe enough to disrupt your life, the best strategy is a combination of therapy, medication, and lifestyle changes (eg exercise).
Easier said than done, I know. I have my own issues I'm struggling with and I get it. I'm in the midst of trying that same three pronged approach.
Please also understand that these diagnosis do not all have the same consequences for not treating them. If you don't want to pursue formal diagnosis and treatment, that is your right, but I would urge you to investigate whether or not you are bipolar in any case. If you have your first manic episode, and you don't understand that is what is happening, it could be dangerous. What you're describing sounds more like ADHD to me personally but is not inconsistent with hypomania either. Again, not a doctor, grain of salt.
