Getting an abortion

After I accidentally got pregnant by my roommate's boyfriend, I decided to get an abortion. Part of me regrets doing it. It was a life, a person who could have been someone amazing. But part of me knows that I would never have done otherwise. I couldn't let my roommate know I was sleeping with her boyfriend; I didn't want my mom to know about it. I didn't even want the boy to know I was pregnant, and so, alone, and in secret, I went and had my child killed. I feel guilty about it whenever I think about it and doubt if it was the right thing. But it's over. I can't change the past.
