OCD?...
I am an EXTREME perfectionist. If the DVD's aren't lined up properly, I have to fix it. If I didn't wash my hands RIGHT before I brushed my teeth, I have to wash them again. I have to write every number precise. I have to spin around in my computer chair. I have to have every speck of food off the counter before I cook. Structures have to be shaped right. No one can touch me accidentally. I any of these things go wrong-I FIX THEM or FREAK OUT!!! Is this normal?....Do I have Obsessive-Compulsive Disorder/Neurosis?...
I suggest you make a conscious effort to mess things up and refrain from fixing them. Put a towel on the hanger crooked. Place a shoe on the floor at an angle toward the other. Leave some food out on the table countertop and unsealed.
Try to get some rigorous exercise, it will help relax your mind and free your body. You are too preoccupied with petty miniscule things. If you do not seem able to cope, then seek professional help.
Your descriptions sound like serious issues that go far deeper than you articulate.
Bottom line: Go with it, whatever makes you feel "right". Everyone is different, and there's nothing wrong with being "different".
If you don't want to live with it you'll need to seek a professional to help you learn how to control it.
Good luck!
