Does anyone else think “oh I’m not having intrusive thoughts right now” and then that triggers the intrusive thoughts? It makes me scared that I’m trying to think about them and I hate it.

It happens all the time for me. It's like you realize you're not thinking about a pink elephant so then of course that's what you think about. But really no, you're not "trying" to think about them. It's just OCD wanting to stay relevant in your mind. OCD can be relentless about wanting to have your attention and will look for any opening to jump in. Whenever the thoughts do come, just acknowledge that they're there, don't try to push or analyze them away, and try to keep on with your day as though those thoughts weren't there.

Yeah happens to me too

That's how they happened like half of the tim

Yes. It feels like a snowball rolling downhill, gaining steam.
