Just to elaborate:
She's just saying that the whole abortion thing is not as simple, that she can still feel bad but not regret it. She thinks that people that feel terrible are a little off and those that feel nothing are either awful or just full of shit. Honestly it makes all the sense to me, I don't think she's doing this for attention, she just wants to tell what her experience is.
Plus she's just honest about all the sex shit, but it's still just shit talking, if you're a guy you've had pretty shitty conversations about girls with all your guy friends, you probably don't even notice but it would make any girl very self conscious. It's the same bullshit with this chick, except that it's girl talk.
