I would go ahead and take it. She wouldn't have scheduled u if she didnt think you would benifit from an extra session and she wouldn't have scheduled it during lunch if she didn't care about you a lot don't feel guilty. Her job is to be available to help you. Let her I think if u are having any hesitation, then it's a good thing u scheduled and extra appointment. I don't think it's a waste of money or time. And so what it your not in crisis mode? I think it will give you reassurance that it will all be ok.
