You might want to consider adoption. There are situations where the adopting family will cover your maternity medical expenses for you. That would allow all of the things you want to have happen: Your child would be born into a happy family, you would be able to continue your career, and - bonus - a family would be blessed with the child they've been praying for.
What you feel in your heart is right - this child is a fighter! He - or she - really wants to be here.
Also, as many of us on this board know from personal experience, challenges can seem insurmountable when we're in the midst of crisis-mode thinking. When we calm down and breath, workable options come to mind. You would find that you would be able to do many of the things you're planning on doing even WITH a child. And, most importantly, once your child is here, he or she will be the most important thing to you and you will wonder how you ever thought you could live life without him or her. Your whole perspective will focus on what's really important in life - the people in our lives.
