Hello Gingernomad, I can understand exactly what you're talking about, because a group meeting involves other people being able to take the heat off you, so you're not necessarily liable to make the decision by yourself, but a group decision needs to be made by consensus.
On a one to one basis then you have to decide what you want to say, without any help from other people, so at times it can be embarrassing.
The medication you were taking can help certain types of anxiety, but among the list, there are many other types that may eventuate from the different situation you're trying to cope with, in other words, one type may not help you with another type of anxiety.
Go back to have these meds reviewed by your doctor, and what can happen is that anxiety can be joined with depression, although I'm not qualified to say, only know from my own experience.
Geoff.
