What would be examples of ERP exercises for pocd

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 :/

Can I hear some examples of specific parts of ERP that has helped you? I've been doing talk therapy for a few years and the major issue I have with it is that I already have analyzed all of my problems from every angle, so I'm kind of just sitting there yapping about it for an hour. I need solutions and things that make me feel better.

Exposure and Response Prevention (ERP) isn't always easy, but as one of the most effective treatments for OCD, it's worth it. If you've started ERP, what has been the biggest surprise you've experienced in learning to resist compulsions? If you haven't started ERP yet, what is holding you back from starting?
