it can be so hard feeling like something is wrong but not be able to put your finger on it. people like this end up bouncing and in your word "Obsessing" about this symptom and disorder and just working their way hypercondriatic like through the diagnostic manuals. It kind of reminds me of the scene in the musical A Chorus Line where one charater is telling about reaching puberty and instead of talking to someone assumed through reading medical books that his natural body reactions was Gonnorea. You can read these until you are convinced you are on your deathbed but the only thing accomplished is making yourself miserable. There is a wayyou can find out what your problem is and that is by going to a psychiatrist or psychologist and asking for a test called Comprehensive Psychological Evaluation. Its an interview with a psychiatrist/psychologist then an IQ test and some computerized tests once all of these results are in the testing professional can tell you what your problem is and how to help you. Good luck. and take care.
