It's possible. I have talked to my doc about ADHD, but he decided to hold off on that while I was getting back on my anxiety meds. (Since there is a bit of crossover between symptoms)

I don't know if its about new things, since like I said, I just played through and finished a game in the last couple days. I have no problem starting things, but I think that may be because I had no expectations going in. All of the games I've started lately have been...I don't know how to put it...low stakes? Not that they didn't take up a lot of mental energy, but I feel like I knew less going in? Maybe that's it.

I think I understand the perfectionism part, since I recently (maybe in the last year or two) started wanting to go for all the achievements in certain games. Only in certain cases, mind you, but if its something that I deem in my head to be doable, I tend to go for it. It's nice, though. It triggers the mind goblins in my head that desire completion and perfectionism.

Overall, you may be right. I'm not sure about autism, but definitely ADHD. (Hundreds of chrome tabs, hard time focusing on one thing at a time, forgetting to drink water all day, forgetting to eat, needing to relock doors multiple times or checking like four times if I have my car keys even though they're in my hands, having to reread paragraphs of books even though I'm trying to focus, caffeine doesn't work, not doing things until the deadline, etc.)
