How long have you had this, lulu? How did it begin? What were the circumstances in your life? Do the symptoms fluctuate greatly dependent on mental state? It might be hard to do with your memory being how it is, but in my view these questions and the answers to them are imperative toward determining the likelihood of a physical source vs a psychological one (and no, getting a clean bill of health from your GP does not "prove" that it's psychological. And psychogenic and psychological are not the same thing either). It certainly could be physical, though i think where is right that you are almost certainly not dying. Sure can feel that way though sometimes.
Unfortunately battling this crap is a unique and individual experience for all of us. We (as in all humans) are desperately looking to authority-whether they really have the answers or not-to tell us what to do in times like this. But there is no one-size-fits-all approach to this, or any so-called "mental" illness. Just check out the treatment options section to see how every suggested option out there, corporeal or existential, has some problem swear by it while it makes others much worse. Many of us are just in a survival and palliate stage at this point, just doing things that make the experience a bit more bearable for the present moment.
