Empty

It oscillates between existence and nonexistence. It takes the form of the material and the immaterial at will. It can be anywhere and nowhere. It is a void, it takes everything and at the same time it has nothing. But now it has come into your life, to fill you and empty you, to destroy you and rebuild you. It makes no noise, but you hear it. It does not move, but you feel it. It does not exist, but you see it. There it is, waiting for you, following you and never leaving you alone. It has already done too much damage to your life and you need to do something. Maybe fill the void. What will you do with this curious entity?
