I think you should definitely call and ask for an appointment. If it's any help, I started out seeing my T for free as an outpatient at a hospital. When that ended after two years, T was also leaving to work in her private practice. I was so attached to her and it took me ages to pluck up the courage to ask if I could see her privately. She was happy I had asked and said of course I could! She also said that she wasn't allowed to suggest it first since she could be seen to be influencing me and then potentially making money out of me. It all worked out well and she was really happy I continued with her.
