Hi there,
I am sorry that you're having a hard time right now. I know that it sounds counter-intuitive, but leaning in and accepting the uncertainity is the path forward. OCD is the "doubting disorder." Now, these doubts can manifest in a million different ways over a host of different themes, but it all comes down to the same core issue: a fear of the unknown and what if's that plays around in our heads. Somethings to take into consideration are that if you're avoiding doing things because of these doubts, that is in and of itself a compulsion. You must lean into the discomfort, seek it and embrace it. It's scary and it sucks, but it does work.
I work in healthcare and I always deal with intrusive thoughts thinking that I may have messed up and somehow accidentally caused harm to someone (even though I know that's not the case). Instead of running away from the fears, I lean into them. I try and not feed my compulsions to the best of my ability (rumination, checking, reassurance seeking, etc.) by practicing mindful and cognitive diffusion techniques that help me to recognize and note that what I'm experiencing is OCD. Sometimes, coming up with a name for your OCD helps. I named mine "Jiggles", which is absolutely ridiculous but it makes me laugh. When I notice an OCD thought pop up I say "Oh, thanks Jiggles, yeah maybe that may happen but that's ok, but I can handle it if happens". By adding that extra degree of seperation, I am learning that I am not my OCD and my OCD does not define me. Yes, it is a part of me and something that I struggle with on a daily basis, but all it is is just silly thoughts. The more that I partake in compulsions, the more it feeds the OCD cycle since my brain sees these thoughts as such a threat.
If you haven't already, please seek care with an OCD specialist who does exposure and response prevention therapy. Going out and getting help does wonders. Know you're not alone, that you got this and that all thoughts will come, and they will go. Nothings permanent. It will be ok. Best of luck to you, take care.
