I am no expert, by any means, but I have done quite a bit of research on the disorder because my boyfriend does have it. From what I understand, you're plagued by obsessive thoughts: plates being not "right", shower curtain not being in the "right" place, room being hot or cold on one side (unbalanced), etc. These obsessive thoughts cause you a great deal of anxiety or, as you described it, physical pain. Anxiety can sometimes manifest as physical pain. So in order to relieve this painful anxiety, you will perform acts or rituals (the compulsions). The constant, repetitive eye blinking to "balance" the hot/cold of your eyelids could be considered one of those rituals. The ritual doesn't have to make sense even to you, in fact, one of the defining features of OCD is that the rituals often don't make rational sense. Usually OCD sufferers know the things they do don't make sense, but they're so tormented by the anxiety that they just feel they HAVE to do it. Unfortunately, OCD is a clever disorder which constantly feeds on itself. The more reassurance you derive from these rituals, the more reassurance you will need to alleviate the anxiety. The compulsions are short-term solutions to the constant anxiety.

Have you done further research? The first thing I suggest anyone do in such a situation is to arm yourself with knowledge. This site has more information on OCD and there are other sites such as NAMI (National Alliance on Mental Illness) or the Obsessive Compulsive Foundation.

If these symptoms are constantly interfering with your ability to live a normal life and if they are interfering with your family's lives, you may need to consider getting professional help. You say you hate the idea of talking to a therapist, but keep an open mind about it. It is very unlikely it is something which will go away on its own if these acts are detrimental to normal functioning. I would recommend doing some more research and there are simple coping tips you can learn on your own about thwarting anxiety. As I said before, OCD is a disorder which feeds upon itself. I'm not saying you have the disorder because I can't really make that assumption from a single post. But it's a definite possibility from what you've described. And, if you want, you can read my post on my boyfriend's problems with OCD to get a grasp of just how bad it can get if left unchecked.

I hope this helps and best of luck to you!
