this is awful

I was convinced that when I sat down to revise my syntheses for comps. that it would go smoothly. I've been thinking for so long about all of it that I knew it would come easily. Think again. I've been sitting in my office working steadily for about 2 hours and I feel no closer to what I wanted to say than I did before I turned on the computer. I no longer know what I want to say about pedagogy and technology. Or if I want to say anything at all about that. I've been doing research for months and honestly... it feels like it's been said. I am utterly lost. I'm beginning to fall apart.
