I think you're jumping to a lot of conclusions without much evidence. You know, the office staff don't always say the right things, but the office staff are not your pdoc. Maybe the receptionist meant you have an unusual last name so that's why the staff would all recognize it. Who knows. It doesn't matter. What matters is that they pass on the message to your pdoc, and that you and your pdoc work this out.

As for your pdoc, you have no evidence that he received your call, that he ignored it, that he rolled his eyes, that he's sick of you, that he's exasperated with you, that he thinks you're a drain or a waste of space, that he thinks you're an idiot or a loser or a nuisance, or that he doesn't like you anymore. A fine story you've made up!

Why not make up one of these:

--Deli's pdoc never got the message.
--Deli's pdoc wasn't even in the office when she called.
--Deli's pdoc had no time to return the call because he had to personally escort a patient to the hospital.
--Deli's pdoc got her message but then got violent stomach flu and had to go home. After the fever broke and he had stopped heaving, he remembered her call and has been worrying all night about her.

Who knows? Those stories are just as apt to be true as the one you made up.

I hope you can talk to pdoc at your next meeting and clarify the phone boundaries. That's so hard, but can you ask him when/how often you can call, whether he will call back, and what topics it is OK to call about? Maybe he, like many pdocs, really wants his main role to be about meds. Maybe he would see the call you made as more of a topic for your therapist and feel he couldn't help. Yes, I know you no longer have a therapist, but maybe one could be helpful with issues like the studying.

If you truly believe you are calling your pdoc too frequently and your pdoc agrees, it doesn't mean you need to go back to your GP for a referral to a new pdoc. You could still stick with the same pdoc but decrease your calls to him to bring your behavior in line with his boundaries.

I think there are lots of options and scenarios here, but you need more info and clarification from your pdoc before making any decisions.

Best of luck on that exam.
