I never had panic attacks. However, when my illness was at it's peak, I would not leave the house. Like others mentioned, if I got a whiff of someone wearing cologne or walk through the cleaning section of a supermarket, I would almost feel like fainting. My legs would get weak and I would feel as if I were going to pass out.
I suffered more from the frustration that I wanted to get out of the house and do things. I just could not. I think that some might mistake it for agoraphobia, but believe me, it is certainly not that. We want to get out and do things. But when you are weak like that, you find out that you had best stay home, for fear of fainting. All I can say is, that it will pass. Given time, it will pass. Just keep exercising, juicing and taking care of yourself. get rid of any and all chemical cleaners in your home. work on your immune system. work on your 'gut'.
