Bottling up emotions, even if done bit by bit, one tiny instance after another, can cumulatively turn into a giant, unwieldy heap of rocks you can no longer tow. You just keep pushing down the angst, pretending nothing has happened, but the truth is it’s going nowhere. If you bury it for too long, the collection of repressed emotions will simmer and eventually boil over in a fiercer form, often at the most ill-timed moments when you can barely afford it.
