Oh, I have so. many.
I think I have some form of OCD/OCPD, because they pretty much control my life. I have the normal, anxiety related ones (nail biting, lip biting, messing with hair and clothes) and then I have some really weird ones that if I can't do, it will stress me out to the point of crying.
I don't do it constantly, but I'll get into these moods where I HAVE to pretend to "type" any word I see. Like, if I'm in the car and I see the sign, I move my fingers like I would if I were on a keyboard and "type out" the words. The amount of letters has to be even, and if not, then I'll combine them with another sign. I don't really know how to explain it, but it's a biggie.
I'm constantly doing this motion with my neck where I have to bend it forwards and all the way backwards (that started as a response to being told the symptoms of meningitis, and now I just can't quit doing it).
If I'm on, say, Youtube, I have a very specific "clicking" ritual I do anytime I pause or press play on a video. I have to click to the very left of the screen, the very top of the screen, the very right of the screen, and the very bottom of the screen before I press the play button, or I will drive myself crazy and start getting anxious. I normally have to do it multiple times. Also, the cursor cannot be anywhere in sight; I have to drag it down to a bottom corner.
Most I do on one side of my body, I have to do on the other. I chew on both sides of my mouth equal times, if I clench one hand I have to clench the other, and the weird one is touch. If someone touches me in one place, I expect them to touch me in the same place on the other side, but since I can't control that, I can sometimes trick myself by thinking about something else and touching myself there.
I don't always do it, but when I'm in my more "rigid" moods, I flick the lights several times when turning them on, and I sometimes have to go back and do it more if I feel like I didn't do it enough. This applies to many things. I stroke things several times until my brain lets me quit, as well as clench my jaw, blink, stretch, say a word, blah blah blah over and over until I am "allowed" to stop.
There are a TON more, but I'll be here all day if I keep typing. I don't know if I should take medicine or what.
