Hi Rita, it's good to hear from you!
My understanding is that synthroid, once it is stopped, stops affecting you soon afterward if not immediately. Synthroid is not actually a drug so once you stop taking it, your body is no longer affected by it. So that would mean that your hormonal levels would start leveling off right away. But hat is something the doctor can better explain. My understanding of the situation extends only to how hormones and Synthroid may affect your anxiety, or other emotional effects of hormones.
I know waiting is hard. But in the meanwhile, try working on some of your anxiety with the resources you have. It will help give you a focus. Anytime you feel stress about your health issues, try something new to alleviate your anxiety. Also, have you tried joining any support groups for anxiety or even for hormonal problems? If you need help finding support groups, I'd be glad to help. Joining a group would help you feel less alone and give you some good information about what others experience. And you can do it on line so you would not have to find one near by your home.
It is difficult to understand why God has allowed this situation for you. But He does not do anything without a reason. And someday it will be clear. My guess is that you will be used to help someone who needs someone to turn to. Your ability to understand and give is perfect for helping someone else!
Let me know how your test turns out next week. And if you want to work on your anxiety and other feelings around what you are going through, I'm here.
Take care, Rita. I will keep praying for you.
