I can't afford an abortion..what can I do?

I am trying to have an abortion but I can’t afford it. It is honestly the worst experience I’ve ever had to go through, since I never thought I would end my first pregnancy. Before you say anything about how I am killing a baby please understand I can’t afford an abortion never mind to have the child. The father walked out of my life and I am in college. not to mention that I used drugs during the first few weeks. I don’t know who to turn to at this point. Do you know of any programs that help girls with this situation?
