Luckily, I'm not a narcissist ... thank God! My mom wasn't either, and the emotional incest was done mostly unknown to her, in a very childlike way.
My mom was VERY childlike .. yet was subtly manipulative in a very small way. I am very fortunate, that she was this way and not a narcicist, and not physically abusive ... actually, she was the opposite, would never let my dad spank me, very protective of me .. and as the books title it, I was "The Chosen Child". Looked good from the outside, wasn't so good on the inside.
Speaking of being 2 different people .. the only way I can see that in me at all, is when I say something to myself .. such as, I like that, and inside my head I answer 'so do I'. That seems strange to me, and shocks me when I do it ... but hey, if that's the only strange way it comes out, that's ok to me.
Lying: I use to lie if it made me get the attention I needed, the love I wanted ... and to be rescued. I never lied just to hurt, manipulate, etc. others. I could take a lie to the extreme, and there are many counselors and psychiatrists I've fooled. I'm not proud of that, but if you ever need me to lie for you, trust me, I'm the best. LOL!
Anything I can shed a light on, ask me ... will be glad to help. I do see allot of the old me, in KC. Some of it is still there, and will always be, but now with maturity and meds ... I can live a pretty normal life.
