Hi, I'm in the midst of an anxiety attack/period for almost two weeks now, and on top of all the usual symptoms (the loss of appetite, loss of interest in basically anything, racing thoughts, and so on) one of them greatly intensified today: chest pain, specifically in the heart area. Along with shortness of breath and sometimes hyperventilation. 

Does anyone know what can I do to help ease the pain? Are there substances that cause or increase it that I need to avoid?

Any help is greatly appreciated.
