Do you mean, that you have hypochondria where you excessively worry about your health?
I have that too, and antidepressants did nothing for it, b/c it is a learned behavior from emotional neglect in childhood. I'm against antidepressants in general as I've tried them, and all they did was give me dangerous side effects.
I have used DBT and CBT to address the triggers for my hypochondria and learned a lot about myself in the process. Do I still have bouts of it? Yes, when something new pops up from a doctor's visit, I worry but then I use learned behavior techniques to cope with the overreaction and panic attacks, which usually works.
It's learning coping skills and new behaviors -- that is the key to overcome your panic attacks related to your health issues. But if you need to be on antidepressants, I will only say those didn't work for me at all.
