10:00 your time. You're not unfixable, like Mayam says, they're just very busy. Call and talk to your sister or friends before you go to bed and fix a comfort food/drink and write up a little speech to say so you can call the doctor's office first thing in the morning. The receptionist will probably take the call, they're usually not too scary, and you can just say something like, "The doctor promised me a referral when he saw me yesterday but he must have gotten too busy and I'm anxious to get started; did he by any chance give the referral to you to put in my folder or can you get it from him for me?"

The first time I was told to call a clinic I did and was put on hold and no one ever came back. I held forever until the phone hung itself up :-) and then I didn't know what to do! I was afraid the receptionist would recognize my voice or something and get angry. But it's not like that. At any rate, I was able to call back the person who had referred me to the clinic and ask them what should I do and they gave me the courage to call back again. This time I wasn't put on hold and got the appointment, etc.

Do you have the name of where the doctor was referring you to? He may have meant for you to call there and he would have called them and set it up so they'd know you were calling for an appointment? If you have the name, you could try that, call them for their appointment and if they want to know about referral, tell them the doctor/clinic's name you saw, etc. and they'll call him back and talk to him or whatever?
