except that, according to your own experience, it eventually leads to you becoming unable to engage with anything that isn't an instant dopamine hit whose entire arc occurs in a few minutes. you just used writing a 3 paragraph comment as an example of an activity that required long term focus.
and to be clear, i have a lot of the same problems, so i'm not trying to come off overly judgmental here. but i view it as a personal problem that I struggle to finish a book these days, or to invest sustained attention in a challenging side project or even, at times, a fucking video game. (i've caught myself scrolling youtube shorts in my chair at my pc, procrastinating playing a video game of all things).
what you describe (and again, what I also experience, maybe to a slightly lesser extent) doesn't seem conducive to a happy and fulfilling life - or at least it seems fair to guess that a life without the dopamine addiction you're diagnosis could be happier and more fulfilling.
