I was hypothyroid for 10 years before I got treated. In the meanwhile I also got proper treatment for depression, made a big difference but I was still so worn out. Finally they did a more extensive test and this time they decided I had hypo, before they just thought the "numbers" said I had it (they claimed I didn't show symptoms...). This time they couldn't deny it. It was my psychiatrist that referred me to a specialist so they had to test me.

When I started taking meds I could suddenly walk miles again. Before, I could barely walk to the cornerstore. It was a huge difference. I can easily see how hypo can be seen as depression because it makes you tired and unmotivated like heck. Hyper can give you anxiety.
