My friend, you think this likely because your family exhibits these traits (genetics) as do your friends(attracted to like groups). You're using two ADHD meme traits, like thinking everyone feels this way and using extra parentheses (for bonus content). I bet you've also been told that you're not living up to your potential (and that's true!).

If you want something objective, have a coffee or two at 6pm and see if you're still able to fall asleep that night. The neuro typical folks would be unable to quiet down their brain.
