What is your weight and height?

Do you get enough to eat? Low blood sugar and mineral deficiency can cause those symptoms.

What about fatigue and depression? Hormone problems can cause panic disorder, but it's usually followed with depression and fatigue.

Adrenaline is causing you to feel those symptoms, but there is a reason why your body is pumping out adrenaline. Cortisol level check in the morning might be a start.
