Hey, I wouldn’t mind helping you out a bit.
As someone who has ADHD, a few of your issues are an indication that you may have ADHD, such as your inability to sit still for an extended period of time, and your frequent “bouncing around” from one thing to another as you lose interest in it. HOWEVER, the LAST thing I would try to do is diagnose myself with ADHD. I would suggest that you get a medical evaluation which would ensure you if you have ADHD or not, because like you said, you’re going in circles trying to figure out your issues on your own.
Hopefully this helps,
