Is it good to correct cognitive distortions for OCD? Or is that another compulsion?

I’ve noticed that I’m somewhat happier also ignoring my thoughts than I am instead of doing compulsions (I’m sick and tired of being sick and tired atp) but I’ve heard you’re technically supposed to do erp rather than pushing under the rug. But idk if I have a thought I just refuse to think about it again and im fine even if I want to do compulsions

So maybe the title wasn't the best to to put it but when you guys start having obsessive thoughts how do you stop them before it turns into compulsions and anxiety?

When I was a child, before I knew this was OCD, I struggled with constant "magical thinking" compulsions (don't step on the crack or mom's back will actually break, etc). When I later learned this was OCD, it almost immediately solved it. Any time I got a magical thought, I would say to myself "that's just an OCD thought. ignore it." and it just stopped coming! Like seriously it fixed the magical thinking stuff forever. But of course the OCD has resurfaced in other ways. So naturally, I've tried to use the same strategy since I had so much success with it previously. But I wonder sometimes if telling myself "that's just OCD" is almost functioning as a reassurance compulsion? I hate how meta this gets. For example, I have ROCD that comes and goes. So sometimes I'll get a thought like "what if i'm still in love with my ex?" and then I'll tell myself "that's obviously just an ROCD thought" and will feel relief, almost like reassurance. But it comes back. So is telling myself that it's OCD a reassurance compulsion ?? It's just so weird because it worked so perfectly as a kid with the magical thinking thing.
