The sentence you write in anger deserves a second reading in another mood.

Anger writes with unusual confidence. Every phrase feels precise and deserved, because the feeling supplying them is real, and what it produces is a sentence aimed at how you feel now rather than at what you want to be true afterwards. The words look different in a calmer hour, which is when you can see who they were actually for.

Write it if writing helps, then leave it unsent overnight, or at least until the next meal. Read it again and ask what result you want. Most of it can usually be replaced by one clear sentence about what you need.
