I let go of negative experiences.

Bad experiences get better storage than good ones. Nine kind comments and one sharp one, and a year later you can still quote the sharp one exactly while the other nine have gone entirely.

This is not a defect in you.

A brain that remembered which berry made you ill has kept the species going for a long time. It is simply calibrated for a world with rather more predators in it than yours has.

Knowing that helps a little. When something small goes wrong and takes over an entire evening, the size of the reaction is not a measure of the size of the event. It is an old system doing its job with too much enthusiasm.
