Is it common for intrusive thoughts to make you doubt yourself?

I don’t know how to explain this so I’ll do it to the best of my ability. Does anyone experience “co-intrusive” thoughts that try to negatively support the initial intrusive thought? Example: Me: “Thank God I never acted on (scary intrusive thought) & I’m getting better!” Intrusive thought: “What a shame you didn’t” These types of things send me into a spiral. It makes me think that it could lead to a desire instead of staying a fear. Like an intrusive disappointment that I didn’t follow through with the thought? It’s been a long fear/obsession & I think my OCD is trying to trick me that the only satisfaction would be to act on the thought. (I know that’s bs) But IS that why it sends me the negative co-intrusive thoughts? That’s the only explanation that makes sense. Then I wonder is it something else? Am I a grenade waiting to explode??? I simply cannot relax in any moment because I think what’s the use if I’m just going to (xyz) one day?

I have been ruminating on why I have been having intrusive thoughts on a specific topic. Anyone know why? Where do they come from? It freaks me out and makes me think that it came from a real memory (I struggle with false memory OCD)

Usually my thoughts go from statements, which I fight all the time, to doubts like “do I” or “i don’t know” but I don’t fight this. I’m not sure if this is progress or it’s the truth. Anyone else feel like this?
