I find it fun to play my characters with various symptoms of my own neurodivergence. And the occasional NPC in a game I’m DMing will stand out this way as well. I find it adds variety and makes things more real and interesting. A great way I found to include neurodivergence that can have game mechanics tied to it is Limitless Heroics by Wyrmworks, so you could check that out.
Perhaps look into the symptoms of ADHD? I had this same issue for a long time, swinging between being hyperfocused and then not being able to stand the task or project for a second longer. Turns out I have ADHD and just never got diagnosed. Now, I have a name for why I swing between these two extremes.
I don’t live in a place without PSN, however I uninstalled because of the malware style anticheat files that a small update tried to sneak into my system. Fuck off Arrowhead and Sony both, no thanks, I don’t need to jnstall that kind of stuff to enjoy games with my friends on PC.
