sounds like anxiety to me.
if u have a poor diet, u can try to take vitamin supplements and see if they improve your mood at all. a B complex could help.
if u google "vitamin b, stress" it should come up with a lot of useful pages to elaborate on this.
hope it helps. :)
no medication im starting to wonder myself if this is all anxiety related but of course i still wonder what could be wrong
it sounds as if these symptoms are a result of your anxiety. OR are you taking any medications for anxiety and/or depression? they could be side effects from the meds.
catch 22 huh?
You would need to have a cardiological workup to determine if it is your heart. (EKG, Stress test, ECHO, and Holter monitor)
