Or, just talk about your feelings. The listener just listens. It feels good to share feelings. Give them plenty of time. There is a sermon in the Talmud that says that Adam complained to God about how hard life was after being kicked out of the Garden of Eden.
Jewish mourners vent their grief by weeping loudly.
Crying is so important that techniques have been developed to re-learn how. Breathe very shallowly, only as deeply as your hand. Breathe rapidly and make a whining or sobbing sound, like a baby crying. Try to get into feeling sad. Think of things that make you feel very distraught.
