There is lots of good stuff in here. I have battled acedia on and off for my whole life, and am going through it right now. I like St. John Cassian’s teachings, personally, and always find when I am given the impulse to return to them, my acedia goes away. He prescribes prayer and manual labor (not exercise, go fix, plant, or build something with your hands!). If prayer is difficult or objectionable to you, you might find some form of mindfulness helpful.

Hope you feel better.

EDIT: Also, sometimes you are just tired and need a break. You know your situation best.
