I have many symptoms of sleep apnea (depression, confusion, brain fog, fatigue, distractablity, hypertension, dark circles around eyes) but I do not snore at all. My thyroid is fine and so are my nutrient levels (I had blood work done). I’m not overweight and I don’t think I have a tumor or something more severe. It’s frustrating because I have all these symptoms, yet cannot get treatment for them because I’m always lacking something for a diagnosis. What could this be?
