It's so stupid, but hey, brain is bad.
I'm Catholic* and a few years ago, my infrequent existential scares development into 24/7 doubting that God exists, doubting that I believe Him, and being afraid of death.
Should have gotten a hint that it wasn't crisis of faith and more brains going bad when the third part of it became "what if I don't love my girlfriend***?"
It took me a while to wise up and go to therapy because 1) it didn't realize it was an option myself 2) once my girlfriend suggested I do it, I was afraid of going as my extremely online brain, infused with years of exposure to American Christianity, basically expected all shrinks to be atheists** who'll go "lol, just stop believing, you big baby".
Turns out, I do have an obsessive disorder, and that is not crisis of faith (or relationship) which SSRIs can stop.
And I've been living quite nicely with it all, except that at the end of 2021, my shrink suggested that I'm healthy enough to go off my pills.
Three months later, I got triggered by the finale of Midnight Mass (a generally good show), and then completely went off the cliff two months afterwards for reasons I can hardly explain.
I basically lost March-April 2022, and now I'm back on double the dose. And I still lack my former resilience to triggers. I don't think I'm going to attempt quitting medication for years to come.
*A few friends of the family got surprised by that last year - they thought I was an atheist from how much I [socialistly] complain about things. That's what Marx meant with the whole "opiate of the masses" thing
**This was in 2016. We're still together <3
***I do have a friend who has rotten luck and runs into libertarians and homophobes, but I doubt that's a trope you can pick up online.
