The Tides

A feeling is not a switch that is on or off — it moves. Six things about how affect behaves over time, each one the lesson of a curve in The Curve.

🌊 Duration — it passes

Left alone, a feeling drifts back toward the quiet middle. A peak is precisely the part that does not last — which is exactly what the mind gets wrong at 3am.

⚓ Inertia — how long it carries

Inertia is how much a feeling carries into the next moment. High inertia means the same event lingers for days; low inertia means it is shaken off by lunch. It is a property of how your feelings move, not weakness or strength.

↗ Transitions — one thing can move it

A single event can transition the whole curve — one message on a flat day. But notice the curve still drifts back after; nothing stays at the peak, good or bad.

🧱 Stacking — recovering matters

A second hit before you have recovered from the first stacks — the curve had not returned to baseline, so it goes lower. This is why "I just need to get through today" is often literally true.

🌙 The sleep reset

Sleep gives the curve a stronger pull back toward the middle than the hours alone do. "Sleep on it" is not avoidance — it is using how the feeling actually behaves.

🔁 The replay — going over it refills it

Sometimes nothing outside keeps a worry going — replaying it does. That loop is called rumination: it feels like working on the problem, but each replay tops the feeling back up. "One thing I could do" thinking picks a small step, does it, and lets the replay stop — and then the curve can ease.

When a tide is not a tide

All of this describes a feeling that MOVES. If a hard feeling keeps returning at full height, night after night, and does not ebb, that is a pattern, not a passing tide — and the move is to take it to someone you trust. The crisis resources below are always one tap away.
