Omg I totally am going through this. I am actually having my Thyroid removed in less than 2 weeks. The sad part is that I also was undiagnosed for years. As some know before I had brain surgery we thought most of my symptoms were caused by the tumor. 2.5 yrs recovering from that and now my thyroid problem is going to be worked on. I have been working out like crazy and my weight only budge up and down by about 2 or 3 lbs. I know I still have a long rd ahead of me but I'm not giving up.
