You can take an online Death-Related Anxiety test involving 34 statements to see how worried you actually are. "If you are extremely anxious (scoring 65 or more), you might consider counsel[l]ing or therapy; if you are unusually anxious (scoring between 40 and 64), you might want to find a method of meditation, philosophy, or spiritual practice to help experience, explore, and accept your feelings about death."
Of course, entire religions have evolved to bring their followers peace of mind about death but sometimes just reframing the notion of death with some wise words can be enough to provide a fresh perspective to even non-believers:
Neel Burton: "All that we can do is to come to terms with death in the hope of preventing it from preventing us from making the most of our life."
William Hazlitt: "Perhaps the best cure for the fear of death is to reflect that life has a beginning as well as an end. There was a time when we were not: this gives us no concern - why, then, should it trouble us that a time will come when we shall cease to be?"
T. Byram Karasu: "You die a little death every night and are born every morning. In between, you lose your grasp on everything you have. Whether one day you can gently go to your death depends on how covetous you are of life."
Science Daily: "[B]eing a mindful person not only makes you generally more tolerant and less defensive , but it can also actually neutralize fears of dying and death."
Socrates: "No one knows whether death may not be the greatest of all blessings for a man, yet men fear it as if they knew that it is the greatest of evils."
Wikihow: "Understand that it's a cycle. People are born, people die, more people are born. Don't feel like you're being called out, and that you have to fear it."
Are you scared of death? Is this a reasonable response or an irrational emotion? How have you overcome such a fear in the past?
