Hi and welcome! Sorry you had to join us because that obviously means you're not feeling your best. I also apologize for not answering your post sooner.
The TSH ranges vary from lab to lab. The range to go by is the one suggested by the American Association of Clinical Endocrinologists. It states that the range should be .3 to 3. So obviously, you are hypothyroid.
Has the doctor put you on medication yet?
What you'll be taking is a synthetic hormone called t4. You'll probably be put on the Synthroid or Levoxyl brand. These are natural synthetics (made in a lab). It's nothing that your body doesn't already have. Nothing to worry about. You'll most likely be taking it for the rest of your life.
Your doctor will start you out on a rather low dose and gradually increase it as needed. It can take up to six weeks to get fully into your system so don't get discouraged if it doesn't make you feel better right away. You may or may not feel a bit worse at first. Don't get discouraged. Your body will go through an adjustment phase as it will have to get used to getting something it had to compensate for in the past.
Take a look at the information archive sticky at the top of the page. There's lots of good information there. Do a seach for American Association of Clinical Endocrinologists. There's a lot of information there.
Good luck to you and again, welcome!
