Things can get out of hand very quickly. Sometimes you don't even see it happening until you're in a whirlwind of mistakes and regrets. As terrible as that may seem, if you just remember that that moment can't last forever-you'll be OK. That storm will pass just like every one before it.
In the end, everything is OK. If it's not OK, well, it's not the end.
Eventually everything will quiet down and you'll only be able to hear the subtle whisper of the wind, and the waves quietly brushing up against the shore.
Just hold on.
