How about someone who has been in this position? With her, no less. My mom decided not to have an abortion with her, but seriously considered it with my little brother (who is like 15 months younger than my sister) because my little sister was only 6 months old when my mom got pregnant again. The point is, my mom felt trapped too but realized that it wouldn't be fair of her to never give my sister a chance. Now it's suzanna's turn to "pay it forward" and she won't do it.
And just so you know, depression after abortion is much more likely that ppd (post-partum depression). Because only a semi-small percentage of women get ppd, but more than half get pas (post-abortion syndrome).
