I don't know much about POCD but I have OCD and the main way that manifests is through intrustive/disturbing thoughts. I have all kinds of things occur to me, all kinds of fears about what if I'm a serial killer/pedo/etc. I know I'm not. But the OCD part, when it gets going, can convince me of almost anything, which is what makes it so terrifying.

I don't think there's anything 'wrong' with you, based on the info you've given, but I certainly understand your concern. The best I can say is that in my experience, even when things surface and stick around for sometimes weeks or months on end, they do eventually lessen with time. Have you thought about DBT? Do you know what it is? I've found some of the skills to be extremely useful in states of obsession/distress. Feel free to message me if you need someone to talk to. Best of luck on your journey.
