Some people just process these things better by forcing themselves to put them into words. Journals, for some people are not written to be read, but to be written.
I was like they in high school. Wrote out my thoughts. Lose-leaf paper in my binder with me other school stuff, so they didn't survive more than a few months. But the writing was the point. No-one was ever going to read them, not even me.
That's the silent one by HPLHS, isn't it?
They did a talkey version of Whisperer in the Dark, and it was pretty damn good. I love their Dark Adventure Radio Theater, too.
