I'm starting to think I have OCD. If I'm watching TV or playing video games, I always make sure the volume is either set to an even number, or a multiple of 5. I hate seeing things asymmetrical. I hate seeing things with no particular layout or organizational style. On my phone and Desktop I organize things into folders so they only take up as much space as either 2 rows or 2 columns (Rows for my IPhone, and then columns for my computer). I'm good in Math and Science, but I hate rounding numbers unless they are irrational. I also check to see if I have all of my stuff in my backpack repeatedly before I leave for school (for homework, books, etc… ). Do I have OCD?
