Jen,
I'm so sorry to hear about your family's reaction!! I would talk to Birthright or a crisis pregnancy center for emotional and financial support for this pregnancy. Perhaps (hopefully) your family may turn around a little bit and be more supportive as they get more used to the pregnancy. If you decide that it would be too hard to raise the child yourself adoption is always an option also. Im sorry this is such a rough time! I know it is hard. You are not alone. Try to hang in there as best as you can. I will be thinking and praying for you. Best wishes.
Kate
