It might sound odd to keep a journal about OCD, but you can use it to measure progress and better see what the major triggers are.
Journal your progress in doing this, or whatever your particular symptoms/fears are. It's okay if you have to write how miserable or scared you feel facing an OCD symptom. This is normal. When we are accustomed to running away from the fears or trying to shut them out of our mind. Facing up to them brings on all sorts of anxious feelings. And the 'OCD bully' in our brains is not used to being stood up to. Eventually it backs off knowing that we will not cower from the fear or thought and threats. We will not give into a compulsion in order to feel 'safe' from empty threats.
Of course, the brain will create new fears and new threats...treat them the same way. "Oh yeah? Go ahead, make my day." And you WILL have a good day from facing up to the OCD bully.
