It appears, at the end of the day, that your choice of applications was better thought out than your friend’s. You seem to have applied to schools that wanted you-- for whatever reasons-- and your friend seems to have applied to schools that didn’t want her. I think maybe it’s less a matter of your qualifications vs. hers than one of realistic expectations.
Guilt should kick in when you’ve done something wrong. You haven’t. You can feel sympathy or empathy, but you have nothing to feel guilty about.
Congratulations!
