don't understand

God I know that everything happens for a reason, but how come she had to go through all these suffering? she is the one who held the whole family together, and what are they going to do without her. God, you took her away because her mission is done on earth, but why leaving such a chaos? why leaving people in such grief? I know you have your good will in these, and I believe it. But why her, and why so hard, so sudden? Yaoyao always fought with her, and now Yaoyao didn't even get a chance to say sorry to her mom? Don't leave her in regret, please! You took her life away because of the wicked deeds of men. You are the unchanging God. Is this a reminder that you are the God who hates sin, who hates disobedience, who hates wickedness? God, please answer all the prayers, and help the family to stand up again. Let them depend on you! Please!
