I'm guessing you weren't the first conference of the day (or, at least, the week), but you were probably one of the few who praised her. It sounds like she's been handed a very messed-up situation there, and while a lot of teachers go home at the end of the day and say "it's just a job, who cares if I can't do right by all of them?", this one sounds like the sort who really puts her heart into it. She's also probably not got a lot of parents who care as much as you do, unfortunately. So I would say don't beat yourself up...from what I can tell you said nothing out of line.
