I am a pregnant teen with no support and having to choose between my family or my baby!?

Try to talk with your parents, if your family is financially capable to have the baby, ask your parents to consider to keep the baby and you go back home. Leave your partner and start a new life with your baby and your family. This is a lesson to learn, but don't turn away from your responsibilities-the baby. Your parents will forgive you, no matter what, after all you are their daughter.
