Grief is hard. It can hit you at any time or anyplace. It doesn’t always come from a death, it could be from a divorce, breakup, losing a job, loss of self esteem, and many other things.
Every person grieves differently. There is no wrong or right way to grieve. It goes through stages denial, anger, guilt, and hope are some of them.
In the Bible Matthew 5:4 says Blessed are those who mourn, for they shall be comforted.
God always provides us with love and hope, especially in our darkest times.
