With intrusive thoughts…I know I’ve read a few things on dealing with them.. mainly, naming the thought and sorta saying “this is ocd, not me”…and then I’ve heard to try to sit with the thought, doing nothing, just letting it be there.. now are those conflicting..? is naming it and saying like ‘this isn’t reality’ actually doing something or are they complimentary? How to utilize both of these techniques?

Someone else should jump in (I've only been doing ERP for a couple of months) but I think it's fine if you acknowledge or realize that it's ok and even to tell yourself that. Where it becomes problematic is if you need to say "this is ocd and I'm actually ok" as a way to avoid/push away the obsessions. Put another way, if you're saying it do sooth yourself and to counteract whatever you're obsessing about then that's bad. If you notice, you're repeating it over and over and that you feel an urge to say it, then saying it is just validating the obsession and making it worse.

Without acknowledging or telling myself that it’s ocd or it doesn’t mean anything (“it’s just a thought”) then it’s hard to understand how to let it be there without becoming fused or identified with the thought itself and basically just continuing the intrusive thought pattern
