Wow, I can understand why this situation provokes anxiety. With my longtime therapist (whom I moved away from for school last Fall), I also saw her at a reduced rate or for free during the majority of the time I saw her. I had a very good relationship with her, and I think you also have a very good relationship with your T. In this case, what I mean by "good relationship" is that I believe that you are both invested and you guys will find a solution that works for both of you. I understand that it's hard not to worry, but do try to have faith in the relationship you have built with your T and that something can be worked out.
