I like to pull the corner of my phone case off and snap it back on

Thumb to finger taps. I do this often, more when getting nervous. I tap teeth to each other, too, feeling like I'm tapping one top to one bottom at a time. Going all the way around to tap all my teeth. I realized I'm tapping multiple teeth each time, but it's a tap for each pair of teeth.

me, a person who's recently begun to suspect i might be autistic:

óoooooooooooooooohhhhhhhhhhhhhhhhhhhh

yep.

• Walking/pacing around the room in circles (I do this very often)
• Shaking my legs
• Twirling my hair

There's been a song stuck in my head for as long as I can remember (decades) that only comes out of the recesses of my brain when I'm alone, and I hum it over and over. Usually this is during driving or focusing on coding. Kinda frustrating that I don't even know if it's a real song or just something my brain is doing for fun. (It sounds a bit like the civil war song, When Johnny Comes Marching Home, I guess?) I'm too self-conscious to do it around other people.
