I have Hashimoto's and I've dealt with depression and anxiety pretty much my whole life. I was finally dx'd BP a year ago. It's definitely a possibility that it's causing some issues with mood but usually it's not extreme. Mine is beyond Hashimoto's. I've also been on Thyroid meds for 22 years and know that even with that, I'm still having issues. Maybe once you've been on Thyroid meds you'll notice a difference. Hugs to you!
