Revelation 21:4 "He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away."
In God's kingdom, there will be no pain, no suffering, no mourning. As such, why would you think that He would allow you to suffer forever in this life? This world is not perfect, but if God will eventually do away with pain, you know that He will not forsake you to it forever. You will recover. You will heal. Your heart will be made whole, and you will cry no more. Trust that God will bring you to happiness and healing. It is not always easy, but know that God is with you. He was with you when He formed you, and He will be with you in the end. He is with you here now, as well. Do not despair. Instead, trust that He will bring you healing.
