Is anybody else having problems with their thyroid?

The reason I'm asking is that I got sick and tired of being given the royal run around and went online and began doing a self diagnosis. I knew the symptoms (3 major ones are weight gain, lethargy, depression) and the one thing everyone kept coming back to was hypothyroidism. The clincher was thyroid problems run in my family. All tests came back "normal", so now I'm self-medicating with a herbal thyroid support blend. The difference is like night and day, my energy levels are up and my depression is almost non-existent.
