If it’s still with you, and to the point it bothers you that much that you post here, any approach is a practice and requires repetition. It won’t disappear immediately. The goal is to transform your thought succession, your automatic responses and thoughts.
Working through it would be considering alternative views on the situation, affirming yourself in the situation, etc
Acceptance doesn’t have to be appreciation. Acceptance that it happened, that it went as it did, it is what it is. You are past it now.
Putting it aside, preferably in a good-willing way, is noticing the thought arises, and putting it aside - if necessary with thoughts or with a affirmation of “I have thought about this, enough, I have handled this, it was what it was, but is not relevant now”.
