How Do I Stop Regretting Decisions I Can't Change?

You do not stop regretting decisions you can't change by convincing yourself they were fine. Part of you knows they weren't, and lying to that part only makes it louder. What changes the regret is dropping the fantasy that you could have chosen differently with what you knew then. The choice was made by a person who did not have your current information, your current pain, or the outcome in front of him. He chose with what he had. You are punishing him with what you have. That is not justice. It is torture of a person who no longer exists.

The structure is that regret over the unchangeable is grief wearing the mask of a problem. Your mind keeps returning to the decision as if it's a puzzle it can still solve, running the alternate version, arguing the case, because treating it as solvable feels better than the truth, which is that it's a loss. It cannot be fixed. It can only be mourned. Every hour spent trying to solve it is an hour spent avoiding the grief underneath it.

There is a real division to make. If any part of the situation is still open, an amends you can make, a person you can still reach, a course you can still correct, then the regret is useful and should move you to act. Do that. But if the door is truly closed, the regret has no action left in it, and continuing to treat it as actionable keeps you circling a grave demanding it give something back. Telling live regret from dead regret is most of the work.

For the closed doors, the shift is from fixing to carrying. You stop asking the past to be different and start letting it be true, including the true cost of it. The regret does not vanish. It stops being a wound you reopen daily and becomes a scar you carry, part of the record of a real life lived by a real and limited person, which is the only kind there is.

This is not therapy, and if regret has curdled into something that won't let you function or keep safe, please reach for a real person. If you want to look at what your regret is actually mourning, the free book Before Approaching the Threshold is a place to begin.
