The thing ruining your whole week won’t even make the list of things you remember a year from now.

Difficulty is loud at close range. Whatever is going wrong takes up the entire field of view right now, and that intensity measures how near it is rather than how important it is. A year from now most of it will have been filed away without ceremony, which does not make it any less unpleasant today.

You can hold both of those at once. Let it be as hard as it is, and also ask whether you would even recognise this problem twelve months out. If the honest answer is no, spend a little less of yourself defending against it.
