Scaredykat,
I'm so sorry - this kind of thing can be really scarey. No matter how hard I try, I always imagine the worst thing. And then I go online and look up what kind of terrible thing this could be a symptom of .... yikes. I freak myself out good.
I have Hypothyroidism which makes you gain weight if untreated. And I think you ar right that having Hyperthyroidism could make you lose it. But you've also got a lot of stress, like you said. And the quitting drinking... I know this would all be going around and around in my head.
I'm sorry. My only idea is for you to try to distract yourself with other stuff until your appointment on Tuesday. Funny movies. Good walks. Visiting with friends. You know the drill. Hang in there and keep us posted!
