Your standards should protect you from your own desperate moments too.

Standards are easy to keep on a good day. Their real purpose shows up in the moment you are lonely, exhausted, broke, or frightened, when the thing you would normally refuse suddenly seems reasonable. A standard that quietly steps aside whenever you are struggling is not really protecting you, because struggle is precisely the condition it was built for.

Think about which of your lines tends to slip when you are at a low point, and set that one up now while you are steady. Make it concrete, and if it helps, tell someone or write it down. Your desperate self is not a worse person, just a tired one, and deserves to be met with something already decided.
