Your story sounds like mine. I'm 37, and had been fine for 10 years on Paxil for depression and mild anxiety. Then I got a new job 2 1/2 years ago that promised insurance than refused to offer it. While self-insured, my wife had major back surgery in the midst of moving houses and was out of commission for two months while the medical bills piled up. My job gets progressively worse, restrictive and stressful every day. This fall I started getting daily headaches and my therapist recommended switching to Celexa. As I weaned off the Paxil, my anxiety skyrocketed and I started having panic attacks for the first time. I feel like my new generalized anxiety disorder (and health anxiety) has come out of nowhere but I can see the stress I've been under for so long had reached its breaking point.
