My first bout of anxiety came in december 2003 after problems with family and right after planning a wedding, just quit smoking. I was very stressed and had this huge panic attack in the airport. Thought I was gonna die. Had a lot of smaller attacks, went on zoloft, was fine. Stopped zoloft about 6 months later. I was fine until this January when I had my miscarriage. Then it was downhill from there. I know what you mean about this spaces between them. You feel like you are cured and then it comes back. I always think that atleast I know what to expect now.
