Everyone knows their own burden
As God's children we must know that the Lord even uses the worst mistake and the deepest pain to mold us into a better person. Everything that God allows to happen to us, always has a purpose. We each have our own life history that should not be judged by those that have not lived it, nor know it. For that reason, do not speak about what you have not seen, nor condemn what you have not felt. Each of us knows the pain of our burdens, the weight we carry, the problems we go through, and the fights we face.
