Hi,  I have been experiencing increased anxiety the past few weeks. Last week I had a episode of heart racing that doesn't calmed down ended up check into emergency room but the test all came back normal/ok.  The last few days I have on and off pain in the left chest area. Does anyone have similar symptoms?  I am constantly worried that something is wrong with my body and that also increases my anxiety.  How do you calm you nerves when ever you feel something.  Thanks
