Narcisists do not overcome anything, not even the victims their apparently discard.
They have a stunted limbic system due to trauma in childhood. It's like losing a limb, it won't grow back. They are unable to feel empathy like normal people. They live in constant pain and anguish, and their goal is to seduce and capture others to make them feel their pain. Empty vessels.
By the man's own words, calling it "overwhelming" and adress it as a "condition" is his way to take no responsability for his behaviour and victimize himself. Typical narcisist.
