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 suggest if you go back to work be realistic. You do have to consider your resume and reputation so be careful not to bite off more than you can chew. Better to take a sabbatical or work a job that less demanding for a while than to continually quit jobs and burn bridges.
