I used to have it quite badly when my first child was born, but got it under control. I'm ok now, but do have to remind myself not to go there sometimes

I can totally understand us crps'ers being more prone to it...
Relaxation is important, OCD is a lot to do with anxiety and stress. It is manageable though, and you can control it, it just takes some work and belief. Well worth the work I promise.
If I can be any help, do message me.
