My Ex wife once told me I had NPD. I thought about and realized she may be right. I think for me it's a way of masking past traumas in my life. I have never been open about incidents of being Bullied in school, which I think caused PTSD. I mask my feelings of inferiority by acting the opposite and I know I'm not better than most. This is the first I've ever told anyone I've been bullied.
