First, I'm sorry for opening a lot of topics in a short time, but I have a lot of questions right now.
So, sometimes when someone says something, I repeat the words in my head a few times over, and at the same time I make hand motions. I touch the tip of my thumb with that of my index finger, either writing the letters there or just touching them once for each syllable. Or I tap every finger tip on a surface, one for every syllable, and feel kind of satisfied when an entire sentence "fits" on an even number of hands. (Yeah.. that sounds confusing even to me now.)
Can this be considered echolalia? And the finger thing, is that just a stim?
