One of the great things about art is that you can actually use it as a tool to navigate and express your emotions. What does anger look like on paper? What does inner calm look like? What colors or marks express angry emotions? If you find that you are too angry to sit and make artwork the way you normally do, consider a different approach. For example, throwing paint aggressively at a large canvas, or something else that involves the movement of the body. How does anger come out in the form of a dance? How do you imagine a more harmonious world to look like? Instead of letting anger be a block, consider that it could potentially become the fuel for great work and self exploration.
