Why is existential ocd so freaking difficult compared to other themes?

My last and almost life long theme/sub-theme largely subsided recently and my ocd felt like it wasn’t even an issue. Then I went on winter break from uni and being alone made my mind come up with a whole new topic to obsess over. TLDR on my fears, my advisor wouldn’t email me back for a while about signing up for classes so my mind started to worry “what if he doesn’t in time and you can’t enroll this semester and you lose this whole life you just built and all these new friends” So when that issue was resolved my mind found other scarier ways I could be uprooted from my current life and friends that I’ve grown so attached to. Then my mind remembered back when I was struggling with false memories and scrupulosity and I essentially made a post on a forum 2 and a half years ago saying I did something or was convinced I did something that I never actually did. Now I’ve been spiraling about someone finding it reporting me and I either get seen as a horrible person or arrested or something over something I never actually did but “admitted” to out of fear of going to hell. My mind won’t let it go and keeps finding new reasons for it to be “valid” “logical” or even inevitable. I feel like it’s just hanging over my head and I can never rest easy. Especially when I try to focus on my daily tasks or plan for the future I get this horrible flair up of “why plan for the future when this could come back in that future and you get uprooted from all of it” my mind won’t rest without certainty being uprooted won’t happen but certainty doesn’t exist, at least not with ocd. This sucks and I miss being care free.

Hi guys! I’m new to the community and I’ve recently received my OCD diagnosis (tho I’ve known about it since childhood). I’ve been somewhat spiraling lately as I wait for my first ERP session (hooray!) I was just wondering if any of you guys have received ERP for existential OCD and if it was successful? My existential OCD compulsions are more so mental and have been affecting me in the sense of dream/memory flashbacks and giving me a sort of “uncanny” feeling about everything around me. Any advice is appreciated! Thank you❤️

So with my theme of ocd, ( hocd ) I get persistent intrusive images, and thoughts. It’s not like one or two a day. Like if I’m out for the whole day they’re constant. I feel I can’t even look at a girl now without her intrusive thoughts about her or about me fancying her and even sexual intrusive thoughts.. It’s awful. It’s everywhere I look. Is this common with ocd with any themes? Like is it constant for you guys too?
