It sounds like you like some aspects of meeting with your counselor, despite the fact that she can't do real therapy with you. Overall, do you find meeting with your counselor helps your mental health, or at least helps you to maintain things and not get worse? If so, then the fear of losing her is certainly understandable. There's unfortunately no way to tell for sure what the future may bring, though. If you don't want to ask her about this directly, maybe you could ask her about some general ways of dealing with and reducing anxiety? Is that something she can help with? Or, if she has already made some suggestions, maybe you could talk about those some more, without getting into exactly what the anxiety was about?
