There is definitely a lot of anger that comes out when struggling with PTSD, especially when it comes to complex ptsd. I think this is also connected to some childhood emotional neglect and for some having to live with parents who had their own issues and were not really responsible adults.

It's hard to experience one's childhood through ptsd and see some things years later where you KNOW things you lived through were wrong and even seeing some neglect you suffered. I think that when someone is struggling with pstd, they become very awar of the things that end up causing life long hurts too.

When you find yourself getting angry to the bone as you call it, you need to step back and write it down because it's connected to something in yourself that was traumatic in some way.
