I don't believe in Hypochondriacs. When one is healthy one knows it, and so the opposite. I hope that doesn't make you freak out or anything. The body is connected to the mind, in fact it is the mind! If you feel something is off balance I recommend you believe so. Try going to a practitioner of functional medicine (technically it's a type of NMD). They won't tell you that it's all in your head, they'll take a blood test and probably test every system in your body (thyroid, adrenals, etc etc etc) because they believe the body knows best. But, everybody has their own opinions on doctor types x)
