I completely understand the confusion, and feel in somewhat the same boat. I also have PCOS as well and my weight has fluctuated a lot. Things seem to be going so well, so why am I feeling crappy? It is hard not to judge myself for feeling badly too, and that seems to make things worse. It definitely sounds like you should check into those symptoms you mentioned. I am sorry you aren't feeling great, and I hope you can start to feel better soon.
