If you can, finish the season before you quit. Leaving on a decision feels different from leaving on a bad day.

A decision made inside a bad afternoon carries the afternoon with it. You remember it as clear thinking, but what you were mostly feeling was tired, embarrassed, sore, benched, and that mood does not survive the week while the decision does. Leaving at the end of something is a different act entirely.

If you can, pick a date past the low point and promise yourself nothing until then. Finish the season, the term, the notice period. If the answer is still go when you get there, you will leave with a clean story and no one asking why.
