It comes to everyone someday or another; when it becomes important to shut yourself in and not let the world outside know.
It comes to everyone this way or that; when it doesn't matter whether or not you have anyone to listen to your woes or complaints.
You live with your cracked heart, cherish lovingly your scars, caress your wounds and bandage your soul and tell yourself aloud that you're alone and okay with that.
It comes to everyone slowly or all of a sudden; and you bear it until it heals. But it looks like it has come to me to never leave.
