You also have a dr who can admit when he is wrong, that's a good thing too! Well could be that if he is the best in the city, he has too many patients.

I don't know what you can do in the meantime. Would your GP adjust you meds a little? Pretty hard to do any relaxtion techniques when you are so agitated but worth a shot if you can. Or walking outdoors, something to just sooth you for a little.

When you do get in to see your psychiatrist maybe ask him to help you make a plan for what to do in these cases. He should be able to help you come up with something other than just wait and wait. It would be nice if it was clear and you both knew what that plan was, that might help.
