Blake, I know just what you are talking about. I just finished one on SA and going over it about ten times in the editing phase was a stressor. The one thing I could say is that it does help to continue, the pain and the triggers are real and that is what you need to get across to your readers, think about most of the great artists, song writers, etc. they wrote most of the stuff during their most painful or joyful times, it is real and that is what people need. Your motivated now by the need to get your story out, write when you can and rest when you can. Resting is important, stress can lead to acting out and depression, you know how the domino effect starts. Keep writing, it will help all of us.
God bless,
