yes. I have hypo. I had crazy mood swings and other personality issues (among other symptoms) until I started taking replacement hormone which is doctor prescribed, which I only take half of. I also started taking selenium and iodine supplement in very low dose as experiment and I feel pretty good now. I had to do something about it because I am a mom and couldn't put my kids through that. I was depressed and anxious and it was a rollercoaster. I had aches and pains and my hair was falling out and brittle nails. My eyes sight started going as well. I hope she seeks treatment. There is relief.
