Now we're getting somewhere! One thing really jumps out at me in that log:

3-22 back was hurting. need new mattress
4-01 Woke up with horribly aching back. (I blame my bed).
4-02 I hate my mattress.
4-05 got up with aching back. god damn bed.

I see no mention in the log of it having been replaced. That is a big deal. It may not be the entire cause of your sleep problem, but it is at least a very major contributing factor. You need to replace that mattress immediately, or find somewhere else to sleep.

It was replaced shortly after, and my back problems promptly dissipated. I had only been sleeping on that mattress for a few weeks at the time, having just thrown away another.

Side note: I thought my mattress was giving me lots of back problems (and incidentally sleep problems), and replaced it, and everything was fixed. Some months later I resumed sleeping with a certain very comfortable, too-small blanket. I hadn't realized I had stopped when I switched mattresses. The back problems returned. I got rid of the blanket, they went away. The too-small blanket had caused me to curl up into too tight a ball while sleeping.
