I've seen the preview for this show, Obsessed and it brings back a lot of memories.
When I was in middle school thru jr. high I had OCD. Somehow, by some miracle, not drugs, I grew out of it. And when I watched this preview it's like it all comes back to me. I used to turn on and off light switches 20-40 times. Always had to be an even number. Same with opening and closing the screen door. I remember getting in trouble at school because I turned on and off the light switch in class and my teacher told me it costs 10 cents every time you open and close the circuit. I never forgot that. Maybe that's what helped me to stop because I felt bad that my parents were going to go for broke if I kept doing this at home. But the screen door was another story. My poor dog would be standing outside in the bitter cold, begging to come in and I would open and close the door just an inch or so 20+ times before I could finally fully open it and let her in.
There were other things that I did or things that really bothered me like certain fabrics on my wrists. I would go completely ape shit if the fabric on my wrist was tight and squeaked if I chewed on it. My poor babysitters. They never came back twice. I also did the counting repetition, like in the preview, but I always had to end on an even number. I would never end on number 3, cuz that's just weird. Ok I think I've said enough.
