They start small, the cracks. So small you barely feel them. But gradually, they set in, growing larger each day. So the cracks are no longer cracks, they're fissures, then valleys, until there are hundreds of Marianas Trenches criss-crossing your heart.
Your patch work is useless. You can't tell their beginning from their end. The only option left is to live with them and wonder how your heart manages to beat, how your lungs fill with air, how your legs can still propel you forward when you feel like you're suspended in time.
