I love your observation about the Lord's Prayer. I often end up using it as a framework too, partly because it does feel so complete (also because of course Jesus literally told us to pray like that). I feel you a lot in the urge to otherwise start with "forgive me" part, and I myself still do that a lot. I realize I need to work on practicing gratitude towards Him more often too, which is important to escaping the trap of self-pity I'm so prone to falling in.
