How does it feel when you see too much death of the people close to you?

I cremated my father after his death according to Hindu rituals when I was 5 years old. I remember his lifeless face, the burning smell, the sounds and visuals. I remember everything clearly. And I have seen death after death since then in my family and friends. But I have never shed tears after my first experience. Most people think I am strong minded to not flinch at the sight of blood or death but I am not. I have just buried my feelings deep somewhere. When one by one, all the people close to me passed away, I started distancing everyone. The experiences I had didn't make me stronger like other people think. It made me a coward who hides behind a strong face! How do you deal with such things?

Note: I know some people will tell me to pray to god but I am an atheist. Because I can not fathom the other possibility. If god exists, is he that cruel?
