I truly believe there is a plan and purpose for your child. You have a very tough decision, but having an abortion is not going to make the fact that you were ever pregnant go away.
When I was 19, I did choose abortion and it haunts me every day of my life. It is the one of the biggest regrets in my life and I will never get over what I did. I have, however, thanks to God's grace learned to live with it, but the road has been so hard.
Adoption is a very, very courageous decision. There are so many families that would love your child. Adoption is not like it use to be. There are open adoptions and you are in the driver's seat. You are in control of how you would want your adoption to go. I don't know where you are, but in VA, there is also an agency that will keep your baby for 3 months until you decide what to do. PLEASE don't discount making a good life plan for your baby.
And Please don't make a rushed decision. There is no easy answer. But, God will make a way for you.
If you need me, let me know. I would be happy to find you a place to go to talk about your options or talk to you myself.
Linda
