@BeyondtheRainbow:

I can understand you feeling that staff was being nosy asking for an explanation. I think you did well to say merely that it was your agreement with your therapist. Administrative staff do not need to know confidential information.

I've even BOOKED appointments with my doctor and when admin staff asked why i just said i'd discuss it with him! We all have a right to doctor-patient confidentiality!

Sorry to hear you are depressed now. I'm in the same boat.
