OCD Self-Help Tips:
Relabel- recognize that the thoughts you're having stem from your OCD and be mindful of your intrusive thoughts and urges
Reattribute- realize your thoughts and urges are nothing but untrue messages from your brain. When you realize that a thought is irrational and caused simply by a biochemical imbalance in the brain, you can stop responding to it. Also know that the idea that you can only feel right after performing a certain task, etc., is caused by your OCD and once it's power has been taken away, you will learn to feel right without it.
Refocus- when experiencing an OCD urge, shift your attention to something else, like a healthy and constructive hobby. This is much easier said than done, but in the end, you can learn to train your brain. To begin, whenever you feel the urge to do something, wait fifteen minutes before following through with it. Then slowly up the about of time until the intensity of the urges die down and no longer control your life. A journal can be a good way to document your progress and keep your spirits up if you ever backslide.
Revalue- realize that the feeling is not worth paying attention to or acting on, be prepared for the irrational thoughts, and continue moving ahead (http://www.ocduk.org/revalue)
