CHANNEL THE FLOW OF YOUR EMOTIONS
Emotions have a very liquid quality; they move, they flow, they take on the form of their container. Like water in a stream, when they are in active motion they have a clear purpose and direction; when they get stuck they can become stagnant and even putrid.
Ignoring negative feelings doesn't make them go away, it just makes us unaware of them; but dwelling on negative feelings after they have already served their purpose can keep us stuck in them, stagnant in emotions that should have long since run downstream.
Every emotion has a function. Anger is a response to trespass; when somebody crosses a line or a boundary, we get angry in response, and that anger provides us with the energy and motivation to get them to stop. Fear is a signal that there is danger, and it narrows our focus on that danger, and can give us the incentive and energy to escape that danger. Grief is a response to loss and it can allow us to feel and mourn the loss, and to appreciate what we had.
Our emotions are not always accurate, though...
