The unsent text in your drafts has saved you more trouble than half the advice you’ve ever gotten.

LEADERSHIP
Writing something and not sending it gets most of the relief with none of the wreckage. The pressure was in having it stuck inside you, and typing it out already did that job. Sending does not add release; it adds an audience and a permanent record.
Keep a place for those on purpose, a note app or a paper page nobody reads. Write the whole unfair version, then close it. Look again in the morning, and if one true sentence in there is worth saying to the person, say that one and leave the other forty where they are.
What is sitting in your drafts, and why is it still there?
Free, with nothing to buy inside it.
