I found an article that is very helpful. It is called "The Anatomy of ERP for OCD." It is on a blog called *Reclaim Your Life.* The person who runs it has OCD and is a therapist.
She discusses what proactive and reactive ERP are. One thing that she mentions that really resonated with me is this part: "Acting joyful, like all OCD content is irrelevant. This is the essence of good ERP. And because if I don't, I'll be doing the subtle compulsion of acting depressed, like all this is true, and sabotaging everything I just did."
This part makes me emotional..
