Does ERP work well for somatic?

I have, alongside my other OCD themes, an intense fear of insomnia. Although this has been improving somewhat — partly thanks to medication and The sleep school on YouTube — I still find myself ruminating about it throughout the day when I have something important the next day, I get stuck in the fear that everything will be ruined — for both myself and others — because my mind is so preoccupied with sleep. + a fear of depression coming back. It honestly feels like a form of sleep OCD. I'm not sure if that’s an official thing, but that’s how it feels to me. A form of erp is the idea of befriending wakefulness. That works great tbh. Things like sleep hygiene, meditation, etc. — tend to backfire because my OCD latches onto them and becomes too obsessive about “doing them right.” I’m genuinely wondering whether ERP — for example in the form of a worst-case-scenario audio loop (imaginal exposure) — could be helpful in this case. I’m hesitant to start unless I know it can actually help. Is there anyone who has experience with this or thoughts about it? I’m not looking for reassurance or tips to fall asleep — only for ideas on how ERP might be applied in this situation.

Anyone know any ERP techniques or specific exposures that help with health anxiety OCD? I’ve heard such great things about ERP for other subtypes but I can’t think of any for health related OCD. I’d appreciate any advice!

I'm trying to get my head around ERP. What is the best way to describe how it's a "solution." Imo I think OCD happens with people who are very concerned with their own genuine integrity and probably their own "morality." So when something (like an uncomfortable "real event" that actually happened) messes that up, it's hard to grapple with that...hence the endless rumination and trying to "problem solve" it. But the mind doesn't let you sleep (i.e. OCD) if something is controversial and doesn't sit with you. Or if you obsess over something and it's based on a rooted fear. You just can't "let it go," it has to be addressed and dealt with. But what happens when it is NEVER dealt with? How does ERP address that dilemma as a permanent solution? Or does ERP only address compulsions and anxiety, but it doesn't actually deal with the issue causing it. Do you ever get REAL peace of mind? Or is just something to make you feel "less anxious" etc? Thanks I just want peace of mind. I haven't had true peace of mind in several years.
