I actually feel the same way! When I was younger, I had OCD but it was for different things. Such as me counting corners, counting the stair steps, etc. I thought I then "died off it" and stopped. From time to time my mother still catches me counting.
I have noticed here lately and so has my family members that I am obssesed with change. When Myspace was "cool", I would change the background layout all the time. Now that Facebook is the new cool thing, I change my banner picture, display picture and the About Me info all the time. My Pinterest boards display pics change all the time. It's not just with stuff like that but even my appearance. I change my hair like crazy! As soon as I get my hair done, the same day I'm already looking for my new hair project. My boyfriend liked spending money on me to get my hair done but now he see's that I think about it all the time. So I stopped going to get my hair done. I got so desperate that I let a co worker do my hair. It wasn't even 3 days later that I was already talking to another hair dresser about what I want to do.
My closet is crazy. Once I go out and spend money on some clothes, not a week later I want to buy more. Not so much for the thrill or satisfaction but because I want a different style of clothes. My small check I get every other week goes on clothes or home decor. My room at the MOMENT is themed kind of Hippie I guess you could say. If I had a bigger check, I'm pretty sure that every month, my room would be a different theme. Even if I don't buy anything, I still rearrange my room a lot.
I feel like there is seriously something wrong with me. I hate the fact that I just cant get comfortable with something. My boyfriend and mother is really supportive of me. They try to help but I feel like I still need that change. I dont know if its if I like being in control of how things are or look, or if its I get bored with things, or if I need constant change.
