I found the following blog today and wanted to share it with you. It's about the symptoms of narcissistic abuse. I found it to be very accurate, based on my own experience.

What is interesting to me is that PTSD, often associated with war trauma, can become C-PTSD under constant vigilance with a narcissist. The person gets locked in to the reactive nature of PTSD and can even alter their physical/brain chemistry. What intrigues me is that this is likely how a narcissist is 'made.' Trauma to a young person, constant threat, abuse, abandonment...the list goes on...can cause a person to 'deal' with their life by creating a 'false self,' resulting in narcissism. Brain scans can often find these alterations in narcissists.
What encourages me is that there is help. Don't give up if you find yourself in this situation. You CAN overcome.
