Yup, got it when I was ten (I'm now thirteen). It had a terrible case of it when was around about eleven. I would always want do count to my favourite number (nine) and felt so relieved afterwards. About everything I had to do nine times. I kinda calmed down a bit but now I'm still obsessed with stuff I like (TV Shows, making animation, going on websites, Письмо fanfics). When I'm busy, I get really worries since I can't do или watch the things I Любовь and get quite a bit angry. If Ты met me, I would always talk about my interests. The sad thing is, my Друзья don't know it yet because I'm kinda afraid to tell them :/ They should know since I mainly talk about the things I love, but I now tone it down at school.
I am a bit obsessive about the order of things, but I don't believe I have OCD. However, my mother and many of my Друзья do. I've pretty much дана up on convincing them otherwise and my mom wants to take me to a doctor for it.
