How do I know if I have OCPD?

how do I know if I have this disorder or am just anal and efficent. I can't stand when something is not done a paticular way, but I don't know if it's extreme. So an example is that we had left over pizza and my dad heated it up, but did'nt push the reheat button. So I just could not eat it. I had to wait until it was cold and then put it in and use the reheat button. I knew it was stupid and irrational but I just couldnt let my self eat it. And sometimes I have to touch something or do something. I have to put my clothes on hanger depending on the hanger and the type of shirt, but the hanger is based on style color, what conditon it's in and it get paired with a shirt based on how much I wear it like it. Its more than just normal, but is it considered OCPD? Please help me!!How do I know if I have OCPD?
Yes, that would be considered OCPD. You have to be evaluated by a psychiatrist in order to find out the reason behind your behavior problem. There must be something in your past that made you this way and it can only be resolved by digging deep into your subconscious to trace its origin. The earlier you deal with the situation, the better the chance of your recovery. Good luck.
