Pushed myself too far with an exposure and now regretting it

I’m feeling intense anxiety and have been for 2 days since doing an exposure for a new obsession theme that has been causing me great anxiety for weeks.

I’ve been doing ERP therapy for about 6 months and it’s worked well for much smaller and easier exposures, or even large exposures for other themes.

Without saying the specifics of the obsession or exposure, the exposure is something I can’t undo / can’t wait-out-the-clock to prove that my life will be fine one way or the other IF the fear even comes true within a certain timeline (like if I was just waiting to see if I’d get sick or not from not washing my hands). Now that I’ve done the exposure, I KNOW the odds of my fear coming true are unbelievably low and next to nothing. BUT - it is something that could come true now in a week, month, year, 20 years, 50 years, etc.

I know in reality, I’m probably blowing this fear out of proportion. And most people would NEVER give it a second thought. However, my brain is telling me that I just messed up my whole life by going through with this exposure that has put me in danger. And, I’m angry with myself for doing the exposure in the first place and really regretting it. It currently feels like it would have been better to just keep obsessing about the fear, rather than egging the fear on with the exposure…

Does anyone have tips for what to do when an exposure pushes you too far? What if your anxiety won’t come down? Have you ever regretted doing a super hard/scary exposure before? If so, did your regret end up fading or going away?
