Well, all I can say is Death is a Bitter reality of life and we needn't feel afraid of it. It's common to feel scared of it but as we cannot ignore, so the best option would be to enjoy our life and don't give much thought to Death as it will only increase our anxiety levels. I have seen many try to Meditate, Yoga and things like that and these do help a lot and you can feel satisfied after that. In case, you still feel afraid of Death, think about your friends or parents who are no more as nothing is permanent in this world and we need to adjust with all sort of changes that can affect us in any way. Good luck.
