The tide goes out twice a day at most beaches and nobody panics. Low points can be part of a rhythm.

Some of your dips are not emergencies, they are the shape of a cycle. Energy, mood and interest all run in and out, and treating every low stretch as proof that something has gone permanently wrong stacks a second problem on the first. Knowing the pattern makes it survivable. A beach at low water is still a beach.

Track your own rhythm for a fortnight: when you crash, which days go flat, what tends to come first. Then plan around it instead of against it. If a low stretch keeps going and will not lift, tell somebody you trust.
