Is this dissociative amnesia?

Essentially, all my memories feel extremely faint and distant, and they are growing fainter and more distant with each passing day, to the point i no long "feel" reality, as if my mind was slowing fading away, like i was dying a bit every day rather then all at once. This goes for things that have occurred years ago up to something that has happened a few seconds ago. Indeed, even my own "thoughts" feel equally faint and distant. Its like my consciousness is no longer there, as if it was fading away. All my memories concerning facts and knowledge are more or less intact (so for instance i can still do my job, though not as well as before), its just my life experiences that are disappearing. This has been going for more then five months and those symptoms first appeared within the span of a few days (not sure if this is normal for dissociative disorders). Right now its so bad that it feels as if i just woken up or something, and this happens like every other minute, for the whole day.

Could this be a form of psychogenic amnesia (for the record, i've experienced extreme amounts of stress and anxiety prior to the onset of those symptoms for more then two years. Also, doctors can't seem to find anything physical), and if so, is there anything at all i can do to stop the progress of the loss? I've been reading about dissociative disorders left and right and they all say the same thing. Hypnosis to retrieve lost memories, and therapy to resolve the underlying psychological trauma which is causing the disassociation in the first place, which to me doesn't sound that helpful, since A) i have no specific repressed memories, since i'm losing everything and B) the only underlying trauma which i'm experiencing right now is that caused by the memory loss in the first place!

At any rate, i would at least like know what it is exactly that is destroying my consciousness. If my symptoms ring a bell to anybody here, i really, really would like to know.
