That's good that she responded. Often T's don't want to say much over e-mail--they'd rather discuss things in session (or possibly on the phone). I've had some very cryptic e-mail responses from T's, but then once I've seen them and talked to them, I've gotten a better understanding. I'd definitely go to your appointment. You could always just say you don't want to dwell on why you were hurt, you have other things to talk about.
