Hmm a few thoughts; firstly, regardless of what you're told, if you really do believe there is an issue there, fight/kick/scream do whatever it takes to receive care (not saying you aren't now or anything but) in the end, it is YOUR health and you know your body.
For instance, after multiple attempts at medicating, if you feel you may receive better treatment (say with someone specialised), don't hesitate and be made (directly or indirectly) to feel like it's 'all in your head'.
Secondly, take any suggested meds on here, not worth the bits they encode. Without knowing the entire situation, I see any such suggestions at a minim reckless! -_-
Specifically re symptoms, what you've describe are really (what's called) "non-specific symptoms". Said symptoms alone are really enough to make a diagnosis since many pathologies present like this. Hence really, even with you posting what meds you're on, etc, detailed, methodical series of test would (personal) be one of my first actions - general bloods, test for known disease markers, etc - along with a physical. A complete review of medical/health history. All of which no one here can do and....
.....way before even any (competent) doctor should really even suggest possible dx.
