I am female and I have had a history of bad anxiety. Such as panic attacks randomly with high heart rate feeling of throat closing shakes cold sweat and feeling that I am dying. Also when I tried to sleep the moment I would doze off i would wake in panic with the feeling I had stopped breathing until the point I would fear going to sleep. I stopped going out anywhere if I could because I would sweat an get light headed around people. I have done many tests in the past such as stress tests and tests on my heart. After so long of nobody giving me answers I just delt with it. Now it is not as bad as it was but now it more small things all the time like pressure in my head with a lot of headaches and feeling of my throat closing while I eat or choking. When I lay down to sleep I feel like my throat is closing and places with a lot of people I still get nervous and sweat and sometimes even have to walk out. But suddenly I feel extra moody and sad over everything. I feel very very tired and weak all the time food doesn't give me much interest and I have no interest in sexual activity what's so ever also have had pain in my ovary area as well as cramps. Please give me an idea of what's wrong?
