Being alone in your own house in haunting.
You sit there alone in front of the television reminiscing the person that sat down with you before that's nowhere to found.

You'd sleep alone in a two sized person bed; the emptiness you feel when moving around makes you remember that you used to sleep with somebody that's not there anymore.
You'd eat alone in a table for two, drinking hot coffee yet still feeling cold, eating a hearty meal but your hearts in pieces, you remembered the person that ate together with you, but they aren't here anymore.

Your home was once full of life, noise, and peace, but now it's a wreck.
Depression is seeping in, anxiety is filling the room, your mind is in a constant state of confusion as to why they left.

Your house, which was once bright is now dull.
Your house has become haunted by you, despite you still in there breathing.
The house you loved so much is now dead, and dark.
Ever since they left your house it became dark, not because lights were broken or you didn't pay the bills, it became dark because your heart was broken.
