Everybody has quirks. It is what makes us individuals. I know that I have my own. While they aren’t as severe as yours, that doesn’t make them any less real. I used to have my cd’s arranged by music genre, and then I would arrange each section alphabetically, and then if I had more than 1 album by the same artist I would arrange it by release date. I do the same with my video games. I arrange them by which console, then alphabetically and then by date if I had more than one Final Fantasy or Resident Evil game. As a child I had my clothes arranged by color. I took the time to even make hangers that would indicate where the sections would begin and end. Now I don’t do it by color but I have my clothes separated by style. I keep my jeans together, crops together, tank tops, sleeveless, t-shirts, quarter sleeves, long sleeves, button ups, sweaters, sweat shirts, etc. My fiancee is really bad. He has a thing about restrooms, what he touches with his hands and other stuff.

What you have is OCD and a bunch of people have it in one form or another.

Don’t worry about it. It is what makes you special and unique :)
