Dark and depressing. I thought you did a nice job creating an undulating course, down, up, and back down again. It worked quite well. A few minor grammar things, but nothing minor editing wouldn’t fix.
Words like “didn’t” are used only because it is first person. Someone is talking to you, rather than writing to you. I want to create a sense of story telling instead of story reading. I try to create a cadence with the sentence structure, so when read aloud, you feel the heartbeat of the tale. This is meant to be auditory. Even if it is only audible in your own mind.
