Many of us here seem to have experienced both. Many also experience obsessive thoughts too, or combinations of all plus more. Now that my medications seem to be working for social phobia, and particularly phobia of blushing, it makes me feel like I have a chemical imbalance, and nothing but medication will work. Working on the Panic Program and trying to deal with my exposure work doesn't seem to have the importance it had before. I have been through seven years of therapy once a week, but I have always had to ask each doctor I end up with this same question. Is it a chemical problem, or a cognitive one? It is very confusing for me, because, when the meds work, I believe that there is not other therapy that is really going to make a dint. Perhaps too, those who have more panic out of the blue, when they finally cognitively analyse what they are thinking prior to the panic, realize that there is a reason for it, and then, when learning the reasoning is faulty, understand what has happened to them. But even though I understand the congitive aspect of it, I still can't get it out of my head that unless I am on medications, I cannot cope. I have tried on a number of occassions. But when relief comes in the way of medications, I become convinced again that it is biological. Is there a difference between social phobia, fear of blushing, panic attacks and generalized anxiety, and their origins?
