Here I have tried to create three abstract images to show the stages of losing a pet.  First, I started with anger, with a fierce, sharp image, with a deep red color.  Next is guilt, where you feel like you have casted out or done something wrong.  Finally, is acceptance, where all the colors are the same, and a softer blue background.

Anger- Intense emotion you feel when something has gone wrong, causing stress and irritation.

Guilt- This is a self-conscious emotion involving a reflection of one self.

Acceptance- The act of taking or received something offered and undertake the responsibilities.
