Two wrongs don't make a right (as the old saying goes), and I pray you won't compound your problems by making another wrong decision about your future.
Yes, it was wrong for you to get pregnant–but it also would be wrong for you to end the life of the little child who is growing inside you. I know it's common today to think of abortion as a simple answer to an inconvenient problem–but it is actually a far more serious issue. Your child isn't simply a mass of tissue; he or she is a human being in God's eyes. God told Jeremiah, "Before I formed you in the womb I knew you, before you were born I set you apart" (Jeremiah 1:5).
What should you do? First, you need wise counsel from someone older than you–someone who can talk with you about your options (including placing your child for adoption). Ask God to lead you to the right person or agency (your pastor may be able to help you).
Then I urge you to turn to God–not just to put this problem into His hands, but to give your whole life to Him. God loves you, and no matter what you've done He wants to forgive your past and guide your future. Make your commitment to Christ, and then ask Him to help you do what is right–including mending your relationship with your parents.
