My response to reading his journals became a series of poems, first published by Bill Slaughter in 2001 as "The Conversion of Saint John" at Mudlark. These initial poems, layered with poems written 10 years later, became my first chapbook, "what we owe each other" published in 2013 by O.P.W. Fredericks at The Lives You Touch Publications.
I have recently begun the burdensome process of going through my own journals and notebooks with the goal of gleaning the bits that perhaps I can turn into poetry, and then destroying them. I've already tossed a few. I've been asked to hold on to them several times by well-meaning friends. But I don't want to alter someone's life so dramatically as mine was by listening in on private and often very painful thoughts. Like Jon, I didn't go to my journal when all was well with my world, I wrote as a way to process pain, and more specifically, to remind myself that I did want to live for a while. But honestly, I don't recommend allowing your journals to survive you. Of course that is for you to decide.
