Pondering death can be tricky. There are several emotions that are involved with the thoughts, from hope of an afterlife to the fear of pain and suffering. Hearing about a person who took their own life, was killed by actions that could have been avoided, accidents and disease, or at the hands of another is always unpleasant. The saying, "they are resting and in a better place," can be slightly reassuring, but that doesn't take away the fact the person is still gone. Grief felt by the survivors heals over time or destroys the soul. Those who are religious believers are not alone in facing emotional pain. All people must face death eventually.
The beauty of most religions is a faith that there is much more than this life to look forward to experience. Every good and bad time here in mortality can be worth much more than what currently can be imagined. For Christians, this idea comes from the the Atonement and Resurrection of Jesus Christ where his mortal teachings are more than morals to live by because, "if in this life only we have hope in Christ, we are of all men most miserable" (1 Corinth. 15:19). How precious it can be to open the scriptures and read about Angels and Visions given to mortals as a witness that our person continues long after death. Joseph Smith said, "The things of God are of deep import; and time, and experience, and careful and ponderous and solemn thoughts can only find them out. Thy mind, O man! if thou wilt lead a soul unto salvation, must stretch as high as the utmost heavens, and search into and contemplate the darkest abyss, and the broad expanse of eternity—thou must commune with God" (History of the Church, 3:295). To live by faith is life eternal.
Despite the great blessings promised with faith, everyone experiences doubt. Perhaps all that we have been taught and come to believe is not true. The alternative is absolute darkness. Once our lives are over there will be nothing. It is a scary and sobering thought. While Joseph Smith discussed a vision he had of seeing family and friends rise from the graves on the day of resurrection to once again meet and hug them, he said, "More painful to me are the thoughts of annihilation than death. If I have no expectation of seeing my father, mother, brothers, sisters and friends again, my heart would burst in a moment, and I should go down to my grave." (Teachings of the Prophet Joseph Smith, p. 295). It is hard to imagine living with the idea that first we are here conscious of existence and then some day we are not.
