I went thru a period similar to this after my second RAI . It took a year or so for my dose to take control and reduce my levels. My liver function was very bad for a while as well. I eventually researched how to flush the liver and was surprised to learn coffee could do that. Including decaf as the caffeine is not good on suppressant dose of thyroid hormone. So I found a good cold water decaf method, not chemical decaffeinated coffee, and had a few cups a day. Eventually my thyroid levels lowered to a suppressant level. My liver function improved. Although my gallbladder was removed due to some residual problems and I still have a sensitive stomach but not life affecting.
It feels like you are very anxious about all of this and thst can actually increase the issues. It might help to find someone to talk to. To help you process everything you have gone through.
Cancer is hard. It's challenging and emotional. But we all have to process the pain and anxiety and the changes it brings. They are normal feelings to a really hard thing to experience. But remember cancer is not who we are.
Sending you hugs and prayers
