If you struggle with panic attacks then chances are, because they are so overwhelming, you worry about having another one. The last thing you want to experience is that feeling inside, your heart racing, the panic, the feeling of being out of control and all the other symptoms of your panic attack.
And so to avoid having another panic attack, you may start avoiding going certain places or doing certain things. In some cases, you may even avoid going out altogether because of your worry and anxiety.
Recently I was working with a guy who had barely left his house for 6 months because of his anxiety and worry about having a panic attack away from home. Just the thought of going out made him feel anxious and when he did step outside, that feeling of panic would rapidly escalate. It was so severe that he just decided he was better off staying at home.
Yet a few sessions later and he is out and about every day and doing more and more things.
