Re: Narcissistic abuse and obsessional thoughts
Move away from narcissist(s) and break communication completely. Develop new bonds with encouraging, bright, and giving personalities afterwards. After you've gained the a-hole attitude, it's ok to communicate with narcissist once in a very long while. If they step on your a-hole toes, then you will not stand for it, drag the narcissist out by exposing him/her, and break communication once more.
You won't get over this unless you break contact and develop new bonds away from narcissists. That does not mean you won't deal with more narcissists, but it does mean you will have control over how close you will allow the new ones into your life.
What is your dream? Follow it instead of the "what ifs" doubt, develop that confidence through experience dealing with a multitude of people, and reflect on the self daily to shape the person you REALLY want to be. Read, read, read whenever you can about anything. By expanding your mind, you will overcome.
