How do you deal with post thyroid removal mood swings?

I had my thyroid removed in March and my mood swings are crazy. Before I had it removed I struggle with anxiety and toward the end was having almost daily panic attacks. My doctor thinks I was experiencing a thyroid storm. But since removal i’m angry all the time. I’m also just very unhappy. It unlike anything I have experienced before. I’m guessing it is tied to my thyroid removal. My life is pretty stress right now but I’m usually pretty decent at handling stress. I’m desperate, what has helped you? Any supplements? Diet changes? Working out? Im debating returning to my anxiety meds. Thank you

Edit: I think im due to test my levels again. Last time they were normal and my doc was hesitant to do anything despite my concerns. Which fair, I understand we are shooting for within range.
