The way healing from PTSD caused by childhood trauma is this:
Suppose you have some terrible emotions from your childhood. But you can't really think about those emotions because whenever you get close, you recoil with pain.
Now, I had very difficult feelings from my mother. (I'm sorry this is close to Mother's day). My mother was a very difficult person. So I would watch the movie: Mommie Dearest. Many episodes from that movie would bring me to tears. Those tears represented PTSD wounds. OK, this sounds crazy, but that's where the healing took place. When the movie brought out those emotions in me then they were amenable to healing. The movie brought out emotions which I could not deal with on my own. I watched the movie a couple of times and then I became aware I wasn't reacting anymore. That was because those deep hurts were actually being healed.
That was the healing of PTSD in me involving mother-hurts.
To experience healing from other kinds of abuse, you have to have a movie which resembles or represents your hurts.
There are lots of movies about difficult mothers. I can post a list if desired.
For a movie which brings out hurts from physical and emotional abuse by a father, try watching: The Pellet (English title) . It's a Spanish movie with English subtitles. In Spanish the name is El Bola. It is a movie about a boy who was emotionally and physically abused by his father. You will understand this as you watch it. If you had father abuse, this movie will probably bring the emotions out. It's an interesting movie, but I'm talking about healing from PTSD wounds.
