Just lost someone dear to me this afternoon, need help calming down?

Hi, I learned this afternoon that a very close friend to our family has ped away. She was like a mother to me, I have no one to console me, my mother and father are taking this a lot better than I am. I am having trouble facing that she is GONE. I am crying as I type, just hoping I can feel the peace everyone else does. Her family seems peaceful, but they're close to God, I am not. I feel like resenting God. She was 54 and had Adult Respiratory Distress Syndrome, causing her to breathe through a ventilator. She was asleep for about 3 weeks (induced comma), and today she ped. I am having trouble accepting this, I was sent home early from work because I kept on crying. I know death is never easy, but for some reason, everyone else seems stronger than me.
