Hypothyroid Troubles

I've been feeling really bad lately. My lower back and my legs are so weak I can hardly stand for longer than ten minutes. Not only that, but it feels like my muscles have decided to start a revolution and separate themselves from my bones. It does not feel good at all. To top all that off I have been having migraines the past few days, which just makes me so happy (note the sarcasm there). I'm worried that I am going to end up in a wheelchair from my muscles just wasting away. I've got skin rashes on my hands that won't go away, my face (the right side) gets incredibly hot and I'm just sure it is going to burst into flames at any second, my lower back hurts but I can't tell if it's muscle or my kidneys, I'm incredibly depressed, and I don't go see my doctor until Friday and even then I'm not sure if she's going to be able to provide any answers. I'm sick of being tired and tired of being sick...

Am I a complainer or what?! :) But at least I got it all down and now hopefully it can get out of my head.
