Confession feels like dying for a minute and breathing for the first time after.

Before you speak it, a secret has a size it borrowed from your imagination, and keeping it took constant maintenance. Confession collapses that in a sentence, which is why it feels violent and then unusually light. The relief is not that it never happened, it is that you are no longer carrying it alone.

Pick one thing you have kept back and take it to God in plain words first. If a person needs to hear it, choose someone safe rather than someone convenient. Do not make a speech, just say it.
