It's just a shot in the dark, but I thought about it.
Last year my GP felt a lump on my thyroid and it turned out it was a thyroid nodule. I had an ultrasound on it, and had a biopsy. (god that hurt.) Anyway, the biopsy came back benign. I'm glad that it was benign, but nothing else has been done about it. They didn't check my thyroid levels or nothing. They never called me back for a follow-up either. I've been on ad after ad for three years now and nothing has seemed to work. I'm depressed, have social anxiety and anxiety attacks, and have pretty bad mood swings. Could there be a possibility that this thyroid nodule is causing hormone levels to be out of whack?
