It does seem a strange thing to count suffering as joy, yet there's a truth here in that suffering helps to build one's character. Some of the most beautiful people I know are those who have passed through the flames and come out strengthened. If it happens to clay, why shouldn't it happen to us.
Compassion is an aspect of Divine love that melts all defenses and resistance when anyone's suffering is really seen. There is nothing the personality can do to create compassion, but when we are willing to be completely open and truthful about whatever we are truly feeling, it arises naturally and soothes our hurt. (We could say that truth without compassion is not really truth, and that compassion without truth is not really compassion.) The Divine love that seeks to express itself in the world through us is a powerful force that can break through all of the old barriers and untruths that have accumulated in us.
