Ready for the test?

I have used CBT to help with my checking compulsions for a long time now and found it quite effective as long as I really make an effort or it slips back again. Of course there is always a compulsion to check which I resist and this is accompanied with a sense that I am taking a risk in resisting - such as OCD is. I find now though, since I have gained a better understanding of the reasons behind my needing to check the sense has decreased somewhat making the compulsion weaker - or maybe my resistance is stronger because I understand? I am not sure which. I think I can deal with the checking most of the time. The big test will be for my generalised anxiety disorder when there is an incident which makes me unduly anxious. Will I be able to rationalise it now knowing why I have such fear?
