What are some examples of ERP activities for POCD? And what I should try to be doing when the anxiety and doubt come?

What ERP or other techniques do you use to combat fear of cancelation? Especially curious about those with taboo thoughts, false memory ocd and event ocd based off of real events where the fear of cancellation may actually hold some validity. I once did my own ERP not under a therapist but just on my own I decided to create an anonymous account on Twitter and defend a friend who was receiving online criticism. I knew that this would be semi-controversial so I was expecting backlash and when I recieved troll replies it actually seemed to be a really helpful low-stakes exposure activity. Is this something that others have done? Low stakes online posts etc. that you know will recieve negative responses? I have had severe OCD as a kid as pretty much every subtype under the sun, and as an adult I pretty much have all the types under control except for this real event and false memory and taboo thought OCD. It seems like a different beast since it's somewhat realistic in the camcellation culture today, and it's confusing to address. Ive shut down almost all social accounts and it's keeping me from progressing in a career where I need to have an online presence :/

I used to get caught in a loop with existential thoughts very frequently. Every question made my stomach drop: (TW: existential questions) … … ... "Why does anything exist at all? What will death be like? Is anything even real? Is there any meaning to this? Is the universe infinitely big, and if not, what's beyond it? Are there multiverses? Has the universe been around forever? Will the universe end for good, or will it keep going forever? What is forever like? What even IS reality?" It would get so overwhelming that I remember lying on the floor in a fetal position for hours because I felt like there was no escape. I spent most of my days reading articles and watching videos about theoretical astrophysics and philosophy in a desperate attempt to "figure it all out." Of course that only made me more anxious, raised more questions, and kept me trapped in the cycle. Things started to improve once I learned to turn TOWARD reality, rather than away from it, and ERP really helped me do that. I learned that these questions weren't the problem. I learned that I can actually handle the anxiety that arises when exposed to these ideas and concepts. I don't have to figure anything out to make the anxiety go away; it arises and passes away on its own. Ironically, bringing myself into the present moment and becoming more aware of reality helped me escape the cycle of existential dread. Because of that, this topic no longer takes over my life. If I'm triggered by something I see, hear, or think, I may still feel a little twang of anxiety, but then it just goes away. "Maybe, maybe not" has been the single most useful phrase of my life. Do you ever get trapped in a cycle of existential questions? Are you worried that the ERP approach would be too scary to handle? If so, I'm happy to give my advice.

What would I do for ERP if my OCD says because I didn’t do something correctly or remember something I will have panic attacks that don’t end?
