Have you ever been checked for adrenal insufficiency? This can cause dizziness, numbness in hands and feel, out-of-sorts feeling and also, anxiety! And the more anxious you are, the worse the adrenal insufficiency gets. Sometimes it's called adrenal fatigue. I was diagnosed years ago and whenever I get dizzy I know I'm having a case of low adrenal function. The more I rest, the better I feel. Yet I feel worst in the morning. The doctor said it's because your blood sugar levels are effected too, and not eating while you sleep means you wake up with really low blood sugar, and that makes all the symptoms worse.
