For a while it genuinely feels like an ending, and then, with no announcement, it turns into a beginning. The old self is shed rather than destroyed, and the version that emerges is harder to wound, harder to fool, and quietly grateful for the damage.
The change is neither chosen nor gentle. You come apart because you have to, and somewhere in the mess a harder, clearer person starts assembling out of the parts worth keeping.
The music breaks and then hardens, despair with an edge of resolve. A collapse in the opening that slowly finds its spine, a groove that gathers weight and starts, against the odds, to move forward.
This is the arc's turning point, the low that starts becoming a beginning. Play it on the far side of the worst of it, when you can feel yourself changing shape.
