come to terms with death

They say life is short, and death comes with no warning, Also I’ve heard,and come to believe it comes in three’s. Last year both of my husbands grandmothers died, shortly after his cousin, who is my age (20) also passed away. When she died, I feared my own death, b/c it hit me how fleeting life is, and we should not take for granted the ones that we love, and every day that we wake up. After last years three, I knew that this year was going to be a good one, nothing bad COULD happen b/c of everything last year. My Granpa passed away in February. And my great granpa, a short two weeks after my granpa. Should I fear the inevitable? I try not to and just go about my day’s as care free as possible. But the thought is always lingering in the back of my mind!
