Unexpected Loss: Help This Family Cope

My name is DAD! I am a father of what used to be 4 blessings from God, and then this. He has called my son back to him before my time of being able to prepare a space for him. We all think we will watch our children grow, and never do you think that your child will go before you, but God shows you that life happens for reasons unknown. We're taught to treat our struggles as teaching lessons to be learned. I'm having a hard time understanding this lesson. My CHILD is gone, his siblings don't understand, I don't understand how to explain any type of reasoning for my other children. I'm numb, I'm unprepared, I'm hurting. WE are hurting.

Funds will be used for funeral cost thank you and GOD bless
