It is important not to suppress your feelings altogether when you are depressed. It is equally important to avoid terrible arguments or expressions of outrage. You should steer clear of emotionally damaging behavior. People forgive, but it is best not to stir things up to the point at which forgiveness is required. When you are depressed, you need the love of other people, and yet depression fosters actions that destroy that love. Depressed people often stick pins into their own life rafts. The conscious mind can intervene. One is not helpless.
