Agoraphobia & Social Anxiety Support Group
Agoraphobia is an anxiety disorder, often precipitated by the fear of having a panic attack in a setting from which there is no easy means of escape. As a result, sufferers of agoraphobia may avoid public and/or unfamiliar places. In severe cases, the sufferer may become confined to their home, experiencing difficulty traveling from this "safe place."

I feel judged too, which, is why I prefer anything that doesn't involve speaking.
I don't really have any tricks... I usually read aloud from a book to losing myself up. I also have mock phone calls or conversations. Being prepared in someway... helps a lot.
I wish I had advice. I just joined this group today because my anxiety and isolation is crippling.
One tip is if you have to make a phone call about something specific like an issue with a bill or whatever you can write down and rehearse what you will say before making the call.
