I don't have Tourette's Disorder, but I do have a tic disorder. I believe the way it works is because I don't have any vocal tics I don't have Tourette's.
I have to breathe and blink certain ways at random points in the day, I also roll my eyes. I can hide it pretty well, but sometimes it attracts more attention than I'd like it to

I think I basically just wanted to say, I know what it's like and I know what you're going through. And thanks for making this thread, it takes a lot of courage to speak out when you're misunderstood.
