Most survivors of narcissistic abuse don't realize what's happening to them for months, sometimes years.
That's not a weakness. That's not naivety. That's exactly how narcissistic abuse works.
There are no bruises. There are no witnesses. What there is, instead, is a slow, calculated erosion of your sense of reality, a drip-by-drip process that leaves you questioning your own memory, your own perceptions, and eventually, your own worth.
