Hi Dylan, I admire your strength and I hope everything goes well. This is a place to get support and a nice community to share thoughts and feelings.

Have you got any self-help books or documentaries you'd like to recommend?

Here are some movies I've watched and relate to in some way regarding NARC parents, though some characters have several other tendencies:

Gaslighting (1940)
Mommy Dearest (1981)
Ordinary People (1980)
Precious (2009)

Disclaimer: some of these movies may be triggering, so you can also read a synopsis/ review or watch a trailer.
