To grow up, and mature, requires that we develop certain habits, understandings, confidence, and even fears, in order to face adulthood and reality.
OCD is a behavioral disorder, or a bad habit.
To be changed, or modified, requires that it be understood as to why it is an unnecessary habit, how it magnifies some risk, or need, that is real, but that we sometimes over react, or excessively react to this fear or need.
There are endless sources of OCD explainations on the 'net, at the library, or local book store.
An intelligent, strong willed individual can probably overcome OCD with the proper understanding of the "who, what, why, when, where, and how" of Obsessive Compulsive Disorder syndrome.
You sound like such an individual, AND, you are probably extremely cute, and smell good to boot! Therefore, yes, you can overcome OCD by yourself, if you are willing to invest some time in learning about the disorder.
I used to check our gas stove many times at night before I went to bed to ensure it was turned off. I was over reacting to a very real fear of danger. I overcame it, and I'm not even near cute, nor intelligent, although I am strong willed and do smell pretty good!
Look at it as an adventure. Make a game to spot yourself doing it, and explain to yourself again, and again, why your actions, or reactions, or fears, are silly and unnecessary.
Master this, and perhaps you will also be able to master the art of manipulating men...their full of germs too!!! Try kissing one without wiping your lips off each time, gargling mouthwash, and spitting it on their shoes, which is a real turn off to guys anyway!
Ok..Ok..just drop the lip-wiping, and continue the gargling and spitting on the shoes, till you are 21!
PS: "Shrinks" are not really shrunken. You would be talking to a normal size man or woman, not a pencil sized human being. Therefore, do not fear them. :)
PS PS: Don't label yourself. You are a human being, not a disease.
PS PS PS: To build self-confidence, every time you see yourself in a mirror, train yourself to turn toward the mirror, examine your image....then cry out in a loud voice "HOT DAY.YUM, MOMMA...THAT'S WHAT I'M TALKING ABOUT!"
or, perhaps not...
Anyway, that's how I overcame my lack of self confidence. Now I'm not at all nervous around strangers, although they tend to be very nervous around me.
Better they suffer, then me!
Peace and Love....Kiddo!
