Any kind of grieving that is not allowed causes a break. In our culture, grieving in public is not encouraged, but in other cultures, it is done publicly. Some cultures have walls where people can cry. We don't have that. We have theatre where there's always the chance for you to face things within yourself.
Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition.
