Death - Hardest Part of Life

Why is Death so difficult to deal with. After all everyone has to die some time in life. But we humans are so entwined with emotions, its difficult to part from your loved ones.
As Doctors, we have to go through lots of deaths of patients. Its not easy to face death. Though we are not related to the patients, it hurts when a patient dies. After all he/she is a father, mother, brother or sister to someone. Breaking the news of death to relatives is the hardest part of any doctor's profession. We try best to save someone but many times its not in our hands. No one likes deaths, its painful, but we have to just get on with our lives.
Ive seen so many young , old patients wid small to grave problems. Sometimes i can't understand the ways of God or Mother nature. Ive seen young 7 month old babies wid such grave tumours, bigger than the size of football. what wrong the young child has done to get such a bad condition, such a life which ended even before it started. It hurts to see the hope in the mother's eye that her child will be cured eventually, which we know its not possible. Thts why we say, enjoy your life to the fullest, make good use of your life, help people, who knows whats in store for you tomorrow.
Life is cruel sometimes. We should rather be happy with what we have. Well yeah Death is the end of life, and hardest part of life. but for some Death maybe the best part of life.
