The inability to self-soothe and therefore outburst when you have emotions is an executive dysfunction that is definitely part of ADHD. As others have said, the degree to which you feel the emotions may have other components, but the inability to quell or redirect your emotions is definitely a normal ADHD symptom.
I've largely done those things too until I got diagnosed, at 27. Since then I did adderall on and off, it works decently for me, however, the effects on my mood as it drains out of my system are not great. Mostly, I become extremely irritable. Lately I've been reading and watching more about ADHD, and Russell Barkley really changed the way I see the issue. I, now more than ever, see ADHD as a chemical shortcoming of my brain and I'm really pursuing the right drug or combination of drugs to deal with issues I've been failing to overcome for decades.
Dr Russell Barkley, a respected researcher in the field of ADHD, basically states that there is a chemical deficiency in your brain that makes it physically impossible for it to simply 'be' better, and that things like behavior modification have been shown to be helpful... almost exclusively when the subject is also on medication. And even when environmental changes can make a difference, it tends to fall on those close to the ADHDer to help set up those accommodations, at least with children. However, with adults there exist the same struggles, just to a /slightly/ lesser extent.
I’m gonna take a couple of 30sec to 1 minute videos for memory’s sake. But also I’m probably not the kind of person this is aimed at. (Obv didn’t read the article)
I ended up watching the whole thing, and then again with my wife. Really solid lecture. I'm now subscribed to his youtube channel and have his book on my kindle, though I've only read a chapter in the last month.
