P.S.- I am on my own path, learning more and working to heal from some profound familial and relational Narcissistic abuse. I've been working on these issues for a little over 20 years, as I strongly suspect it was a range of this abuse from various people in my life that contributed to my own diagnosis of Major Depression and Generalized Anxiety.
It's been mentioned in some of the response posts that it can take a long time to realize what's been happening to you. Even with knowledge of the subject, it can take a fair amount of time to wrap your head around exactly what happened. Give yourself time to heal!
And, for sufferers: You know what you need to do. See a therapist and try your best to change the patterns in your life. And, if at all possible, try and make amends to the people who've also been profoundly affected by your condition.
