Definitely get this... Was psychologically abused by a narcissist 10 years ago and still get phases of rumination about it! But I think it was because I kept the abuse a secret and never told anyone and therefore obsessed over it. Only recently did I tell my partner and a therapist about it and it has helped, I think, to get external validation and talk about it. But I still obsess sometimes, wondering what the heck happened and how I could have been so gullible. It's getting better though, I think because I don't judge or fight the intrusive thoughts and memories anymore. I notice them, and then let them drift away, rather than latching onto them. This has definitely helped!
