Adoption is a good choice. We have four adopted children in our family. Usually the adoptive parents pay medical costs.
Look around, talk to a crisis pregnancy agency. They can tell you about adoption opportunities in your area. You can also work on adoption through the internet. I can't give you any information on how good any of the sites are.
Adoption will most likely be difficult emotionally, but it is a very loving thing to do, and you can keep in touch with the adoptive parents if you want.
