About Death

Why do I think about of death right now? (or 'why am I thinking about death right now?) Because my grandmother passed away last week. Actually, I am not afraid of death, I just wonder if I have any regrets in about my life. Did Am I really be myself? Did Have I hurt someone anyone? Did Have I lose lost my faith? Those These thoughts across cross my mind continuously and can't be stopped running.

(I assume you are talking about what you think now, and not what you might be thinking at the end of your life)
