Wow, sent home for having a tic is horrible! I have tics like those, i do the exact same thing, roll my eyes i dont know why, like out of nowhere, but i also have tourettes. Now growing up i didnt have tics, nothing that were ever noticable anyways, but like when i was 7 or so, i started not being able to control any of my motor functions, like i used to be the master at jenga, easily calm, but then i started twitchin where i couldn't do the simplest things, it was weird. Anyways, did you ever check into tourettes? My tourettes are more on the mild side, thankfully.
