[N]ow that the narcissist is gone, however it happened, puzzling feelings are running through your heart.

Nothing is the same without them and, even if you know you are better for getting out, you still miss them and miss the drama and the high.
But the high came from you. That’s why you are drained and empty now. The narcissist gave you nothing.
