Emotions have their own movement. They move like waves: huge tsunami waves, choppy rapids, or long slow tides. The best way I know to work with emotion, especially strong and difficult emotion is to let it move like a wave, allow it to complete its movement and, eventually, to leave. If the movement gets held back, if it gets trapped and stagnates, or an inner turbulence stirs, the unexpressed emotion and grief can turn into physical illness, fatigue, depression, anxiety, or other displaced emotion.
