Damn You, Thyroid.
Yep, I'm hypothyroid. Gotta take pills every day for the rest of my life. Woo!
The most important thing that I could say to someone that's got a thyroid disorder (or any disorder, for that matter!) is to never let a doctor tell you that something's right or normal when you know it's not. Don't let them push you around with their fancy-schmancy lab tests and their big degree. Doctors are just human people, and are just as likely to be unsymapthetic asshats as anyone else. Make sure your doctor listens to you and treats your SYMPTOMS, instead of basing your treatment off a magic number.
You can feel drastically different at a TSH level of 2 than you do at a TSH level of .85, and both are considered normal and even quite reasonable by most doctors. It's critical that your doctor work with what's actually going on with you symptom-wise to get your levels where they need to be.
And! T4 (Synthroid, Lexoxyl, levothyroxine) are NOT always the only solution. A lot of people need supplemental T3. If you're not feeling right on your meds, talk to your doctor. If they don't listen and make changes in your meds, find a new one.
