Over the years, I've noticed a common observation that a lot of OCD sufferers have made after performing an ERP. They will often consider their ERP a success if they didn't panic or have a lot of anxiety or if they did not feel too bad afterwards. Please do not use your feelings as an indicator of whether your ERP was a success or not. It's not an accurate measure. How do you know that an ERP was a success? It's the fact that you did the ERP in the first place!! And the less you compulse after the ERP, the more effective it will be. (You don't want to undermine all that hard work with compulsions - because that is what compulsions will do.) One of my very biggest ERP successes brought on some of the very worst anxiety I have ever felt. And that's ok! It just meant that I was facing a fear that was really huge. It's not about how we FEEL - it's what we do in spite of how we feel.
P.S. Ironically, after repeated ERPs, the anxiety will usually go down over time. However, it's important to note that the goal of treatment is not to reduce anxiety, but to learn to tolerate anxiety, which, yes you guessed it, eventually brings the anxiety down anyway, and on and on we go in a circle of irony!
