Obsessive thoughts about being unable to sleep are causing insomnia. Has anyone experienced this or have any advice?

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.

I feel like it’s just me. But at night when I start to fall asleep, play on my phone, or watch TV; I’ll get major intrusive thoughts and a butt load of anxiety. Has anyone felt the same about this? How have you managed it? It’s getting exhausting and even causes me to sleep-less.

Does anyone have any tips on how to sleep with harm ocd, I’m always so tired but I can’t fall asleep until it gets to the point my eyes won’t stay open, I’m scared that I’m gonna do something in my sleep or my thoughts just eont shut up and it causes issues with sleeping, advice needed please
