You are not alone, not any longer there are alot of people here with health anxiety including myself. Your symptoms sound like anxiety probably brought on by the stress you are under, trying to reduce your stress will help. Have you had the EKG yet? I'm sure it will come out okay, but it is always best to rule out all physical stuff first before blaming it all on anxiety.
