Teen parent?! HELP!?

I am a teen parent. I had my child around 3 years ago, and the only way I can find solace and continue through life is through my prayer to worship of the dark one, Satan. Don't judge me. You have no idea what I have been through. Problem is, my local sect is demanding a sacrifice this coming Wednesday. As nobody else in my group has a child, and our Satanic Handbook says that, unless we sacrifice a child on this specific date, Yahweh will come and destroy us with his cleansing light. So I am at a crossroads. Should I sacrifice my child, or suffer destruction at the hands of the Holy One? I honestly do not know. Any help here?
