afraid to die

I’m most afraid to die when I feel most alive. And I feel young and full of energy, like all of life is ahead of me, then I am afraid for it to end. When I am closer to death, sick or feeling old and spent, then I am less afraid. Sometimes I am in pain and the pain of death seems like it would be lesser than what I am experiencing. I feel that I have less to lose. The fall would not be as great from an already low state, whereas when I am up high it would be a long way down.
