Sorry I'm going to be blunt but what you want is completely unreasonable. Your therapist is moving to help her daughter with her grandchild. What did you expect exactly? That you're such a precious client that she wasn't going to move? You're a client. Of course her family matters more than her clients, it's the case for everybody. As for the financial issues of having to pay another therapist, I don't see why it would be her responsability to ensure you pay a lower fee. If you can't afford therapy, you could go less often. I don't tend to defend therapists but in this case, you sound so entitled that it's making me defend them.
