I think the problems are twofold: the PTSD I have been suffering from as a result of the jobs makes it difficult to write about them and the natural procrastination that I have always suffered from.

I may have to take drastic action! I got through college by buying cakes everytime I had a large assignment. I would write some and reward myself with a piece of cake or pie and so on and so on until the project was done. I once described a difficult project as a "double Entenmann's!" I broke the habit but may have to make an exception. I know it may sound silly but it has worked in the past.
