I too myself have similar problems. It is hard to believe that anxiety can cause you to have so many side effects. Some of them are just frightening. I had the whole chest pains, shortness of breath, tingling, dizzyness, headaches, nausea, etc... I am so restless and scared to be alone or go anywhere alone in case something happens to me.
I am on three different medications, one for my heart because I was experiencing tachycardia, and celexa, and ativan for my anxiety/panic attacks. The drugs cause so many side effects too that I find myself going crazy wondering if I am sick. Lately I have been afraid that I am going to have to live the rest of my life in fear and feeling like crap.
I really hate that I have to be this way. I cannot enjoy life. Hopefully I will get help soon when I see my psychiatrist.
I will keep you in my prayers, we all certainly need all the help we can get.
