I don't have issues but I do certain things over and over again. Like, if I'm cooking and cutting something, I will count the number of cuts I do. Or at work, I work as an enginner btw. I will count the number of strokes I do for some of the manipulations I do and I'm lucky I'm extremely good in mental calculation otherwise it would decrease my performances! loll I often stop at 7 because it's supposely a lucky number. If I have to clean something and let's say I cleaned it in 5 shots, well I'll add 2 just to make 7! Often, I stop when I'm typewriting, count to 3 and continue as if nothing happened. As if my mind disconnected for 3 seconds, it's kind of scary when I think about it... I get mad when people can't seem to to calculate properly and that's so in contraction with my very sweet nature. I'm always kind to others but with numbers, I become impatient, it's really weird. lol

Oh, I also sometimes count for no reason in my head and I love to calculate my heartbeat when I work out. I once almost injured myself because at 6 repetitions on the Bench Press, I should have stopped but I wanted to make 7 at all cost and thank god a friend came to help me because I was stuck with the barbell!

I contradict myself a lot so now I realise numbers DO give me trouble, from time to time.

When I was in elementary school, I'd sort of do light jumps, kick one of my boots with the other and count. I was so obsessed by this behavior and I still can't explain why I'd do that.
