I am a writer too. I found journal therapy to be particularly useful to me. You can google journaling therapy and find a few resources. What I did was to thickly describe my trauma, which included my earliest memory at a child of 5, waking up in the hospital after a coma. My mother was there, briefly, before she had to return to work. As soon as she left the nurses started pricking my fingers to take my sugar levels (the cause of the coma).

After writing in acute detail everything I could remember I also wrote about how it made me feel in detail.

Then I wrote about how those memories and feelings still haunt my behavior and feeling today: sense of abandonment, lack of control...it all led to attachment disorders with my mother and other woman with whom I became intimate with as an adult.

Strangely, after writing my way into and then out of those feelings, I no longer felt like I needed to smoke cigarettes. For some reason, smoking alleviated my anxiety about being abandoned and when I came to grips with the underlying issues my desire to smoke was greatly diminished.

Hope this helps a fellow writer.
