Why do i start getting anxiety every time i get sick or have a headache? i start feeling like i can't breathe and my muscles tense up

See below: Most people can become anxious if they experience a new pain or symptom they haven't had before. Why you are experiencing this every time you get a headache or become ill is hard to say, but certainly is connected, on some level, to a fear of dying. You should see a therapist to discuss your anxiety, it may be very helpful. For more info see: http://bit.ly/104V8hb + http://bit.ly/1z3E1qf
