Death is inevitable. We humans are so naive that we don’t understand that we are not afraid of things or situations that of its consequences.
For example, we are not afraid of fire, but what will happen if we caught fire; we are not afraid of darkness, but what can happen to us in darkness; we are not afraid of height, but what will happen if we fall down; we are not afraid of water, but what will happen if we drown, and the ilk. Ultimately, we are afraid of death.
Once you accept wholeheartedly that you will die when you are supposed to and different things or situations would just be a medium to take you from this universe to a different universe, from that moment you will start to defeat your phobia rather phobia of death. And, after that, you will never be afraid of anything in your life and can actually live your life blissfully.
