Intrusive, never-ending thoughts of, "what if everything is wrong?", "what if our rationality can't be trusted?", and "what if we're living in a simulation?". Those kind. You can't even battle this thing with your rationality as it just keeps going on.

I don't have a diagnosis of OCD, but I do have a *lot* of tendencies and it's the *worst* when it comes to the existential dread. Everything else I can CBT myself and it placates it pretty well, but when it comes to the existential dread it's hard because "if our rationality can't be trusted" then you can't trust CBT. The effect this thing has had on me in the past was pretty bad.

Anyone got any advice?
