If she told the everyone at the hospital she didn't want to go through with the abortion, what did they do, suggest she go through with it anyway? Sounds like that's what happened.
Her boyfriend wasn't happy with her pregnancy. (Big surprise, another "winner.")
If she had a long history of anxiety and depression, they shouldn't have gone through with the abortion.
The only thing the hospital is concerned with is that she "consented," meaning she signed the papers and they were paid.
