I know that things will get better

Nobody can feel a future they have not reached yet. That is the specific cruelty of a bad stretch. The evidence for improvement is all behind you, and behind you is exactly where a low mood refuses to look.

So it has to be done deliberately, and it feels artificial while you do it. Name a month that was worse than this one. Not to prove a point, just to establish that the thing you currently cannot imagine has in fact already happened to you, more than once.

You did not think your way out of that one either. It shifted, partly on its own, in a way you could not have predicted from inside it.

That is not a promise about timing. It is an accurate record.
