Sorry to hear this @StrongCoffee. I don't have much experience with meds for anxiety but I am aware some anti anxiety and depression meds can interact with tamoxifen. I also have hashimotos ie under active thyroid which is an auto immune condition.
I have suffered depression in the past on 2 occasions and required meds to help me get back to a level playing field. One episode was after a marriage breakup and the other after a life threatening illness (not bc).
Now to manage my health including mental health i meditate, exercise daily and try to eat good food. I also have a gratitude ritual every morning and write down 3 things I am grateful for. It is so helpful. I can't really believe the change in how I feel. I started using a gratitude app called Delightful. I think the daily gratitude and my walks each day keep me healthy.
In terms of fatigue which I suffer from I find walking helps. I know it seems counter intuitive but it really works. I have experimented with resting when fatigue and going for walk and hands down the walk works better.
I hope things improve for you.
