Aww! I know exactly how you feel!
I hope it's NOT your thyroid. They finally removed mine. Sometimes, I wish I hadn't let them. Thyroid issues suck for sure! It's harder to lose when you have thyroid issues, but not impossible. It just takes time for your body to become accustomed to good food and make the changes. I honestly believe my weight loss is slower because of this, but I'm a rebel and won't accept that it can't be done!
