SDRL, I am the same way with phone calls. I just hate them. This would be a big source of stress for me too if I were in your situation. You don't have to give much information at all in your phone message or justify why you are calling. You don't have to say you want to resume therapy for OCD and anxiety. THat is a lot of info for a phone call. I think all you have to do is give your name, identify yourself as a former client to help her place you, and say you would like to schedule an appointment. At your first appointment, you can explain why you are there. When your psychologist calls back, I don't think she will quiz you on why you want to see her, your symptoms, etc. She will probably be very professional, which will be reassuring, and she will focus on scheduling an appointment. The phone call will be over in a minute and a half.

Good luck.
