I'm worried about dying in childbirth?

Your going to be fine. Just take a deep breath. You have done this before. It is just you worrying, probably because it is your second child, so you have another kid to worry and think about what would happen to him if you were not there.. etc. You are also going through a divorce with a man that does not care about his kids, so that feeds into this fire for sure. You will be fine, women have been having babies since we were first on earth, women all over the world have happy healthy babies in poor conditions. We are lucky we have proper medical care that it never really happens anymore. My best wishes to you! :D Have a happy healthy pregnancy!
