I hope you find a way to get help. Panic attack can be with agoraphobia. I suspect if I had panic attacks, I would be afraid of social/work situations mostly. You mentioned panic attacks in partial due to lots of people. Can you find a smaller partial group that focuses more on people with panic attacks in social situations. I know that too many people makes me uncomfortable. I have a preference for few people or plenty of room for my personal space due to my odd inability to do face recognition. I would try to talk to someone. Is there a number for you to call and talk to someone at your counselor's office? Can they find a way to call you on the day of appointments? I can understand forgetting appointments. I sometimes lose my sense of hope and lose the ability to plan ahead. I have a friend that has been known to miss appointments because he has trouble keeping track of the days of the week. I have almost zoned myself into being late to work. So, I would ask if you are zoning your days a way? Are you avoiding something? Are you afraid when you leave home? Lack of motivation? Or is it a simple lack of planning ahead ability? Are you really just losing track of time and the days?
