Wow... another thread about narcissism that I'm responding to today. BL must be having a theme week
Yes, one of my parents was a narcissist, but a covert narcissist. He cared about his children but was full of self-loathing and used self-deprication, guilt and emotional manipulation to get energy and care because he felt like he couldn't do anything in life on his own. Unfortunately, my entire family fell apart by the time I was 20 because the way he controlled my mother and his children was non-sustainable. The home I grew up in was mostly pure psychological and emotional warfare. Everything was constantly beneath the surface.
I moved about 3000km away from my family when I was 21 to go to school. It was a good break for me, but I was very hurt. Unfortunately, my upbringing made me susceptible to narcissists. As a gay man, the shitty thing about being raised by a narcissist father is that he was my first male role model, so in my 20's it was easy to accept narcissist partners into my life. And that's what happened.
It has taken years of therapy to truly repair my attachment style and begin to recognize when I am letting unhealthy people in. It has been very hard but I am now coming out the other end of it. I see my value a lot more clearly now and will protect myself accordingly. When you don't understand the pattern, you will underestimate your worth because you are used to accommodating and nurturing emotionally unavailable people in order to experience some security, and so you will more easily accept these kinds of relationships in your life. You will negotiate with inappropriate relationships and with people who will never, ever truly love you because they are incapable of healthy love. At this point, I say no to people who can't show healthy attachment and affection. I've got no time for them.
I got really ill in my late 20's, lasting for 4 years, after my engagement to a narc got broken off. He wasn't the reason for my disease but he was a catalyst. Even though I have been through utter hell and near-death multiple times, part of the gold that I mined from this period of torture was that my body was so weak that I could feel, in my guts, when someone was draining me. If I didn't say no, they would make me physically ill. So now, my body will physically tell me if someone is toxic, even if my mind has delusional hopes about them. If my body doesn't feel good then I need to stay away. I can smell narcs a mile away now and my boundaries go right up. No rationale required. In fact, I have given up on my analytical mind in this department. My other faculties are dead accurate.
