I doubt your a hypocondriac.
As some one who has been severely depression I can tell you it came in ebs and waves, I think that the way AS minds work, and this is just a theory, we rationalize and analyse everything, so often during feeling depressed it kick in and for a while the mind is able to cut of the feelings.
Either way, I would go to the doctor, better to be a hypocondriac, that wait and end up going completely over the edge.
Even if your doctor says you are, look at your emotional situation logically, if you still think you are, dismiss what he says and seek help, either another doctor, or a helpline, a proffesional, etc.
