You will recover. The only thing you have to accept is that you have to be patient. It does not go away overnight, and it will come and go during your treatment.
Just a note about the medications, you will most likely have side effects when you first start an SSRI. I certainly did...clenched jaw, vivid dreams, insomnia, feeling 'numb', loss of weight. The side effects are intense for the first week, then are gradual over the next couple of weeks. Give it a month to three months (it took me three) and you'll start feeling normal. I've been on an SSRI for a year now and I don't have any side effects.
If I could go back to when I first developed panic disorder and thought I was over, I'd slap myself for worrying so much
