First step in the right direction

My name is Sarah, I am 25 years old. I became pregnant with my son Bradley(5) right after high school. Although I love my son very much, I was not ready to become a parent, my son's father was not happy and sadly didn't want him, being pregnant with a child that you love and the other parent doesn't want was heartbreaking. Unfortunately, at the time I was too selfish to give him up. I am now a substitute teacher and a waitress, saving money to get on my feet after my sons dad and I broke up. I feel like I am now working on what my next step is and figuring out who I am and what I want to accomplish in my life. I have two major goals in my life, I want to birth a baby for someone who wants to have a baby as much as I want to bless them with a baby of their own. And my second goal is becoming a foster parent(in 20+ years), I don't plan to raise anymore children for the next 7-10 years and by that point it might be too late. I love being pregnant but I am not in a position to raise a baby, mentally or financially. I would love to help a loving couple have a baby, I am open to all types of relationship , cultures, ethnics, and religions. I don't consider myself very religious but I am trustworthy with a big heart for helping others.
