Perna made a very good point!

From the post alone it shows signs of OCD, just worrying so much over if you even have it means you tend to be obsessive over things. Not that its to a dangerous or life altering level. But as Perna said, try to think of things that do make you worry and see if they are reasonable things constantly worry about. If your not sure, post them up and I'm sure we can all take a crack at it. =)
