Good to hear you are doing well. You are not a Narcissist. I would know if you were.
Two things come to my mind; you have fleas from living with a difficult person for so long (possibly has NPD) and you have been focused on him so long that it feels selfish to concentrate on yourself. We all need some narcissistic traits. It's what helps us set boundaries and care for ourselves.
I have been watching this lady on YouTube https://www.youtube.com/channel/UCkUVh2 ... YwDjE689Wg
I like listening to her weekly Q and A. They are all archived on her channel, Thrive After Abuse. There is also a Facebook group. I love what she says at the end of each video. "You are not alone, you are not crazy and you can move forward and heal from this."
Lately I have been watching Dana every night before I go to sleep for about an hour. I find this has impacted my dreams in a good way. Not as many anxiety dreams; like not being able to find the bathroom or the classroom where the test is being given. I have been having standing up to the bully type dreams and it feels good.
The only bad thing is that I am seeing narcissistic behavior all around me. Also, recently, I find myself being triggered when I read about abuse being done to people. It could be that it was there all along and I avoided looking it. I could just be waking up to something that has been there all along.
Take care of yourself and keep in touch.
