If you’ve been working a lot or are under a lot of stress (kids, too many hours, responsible position, people complaining to you a lot) your mind may simply be locked up. This is a panic reaction, a last defense mechanism for a mind running with hormonal imbalances. It will mean your cortisol is too high early on, then drops off at the time you need it most. Your body’s stress response is worn out and depleted and needs time to regenerate. That’s why burn-out victims are usually told to go home and do nothing for a year. It takes a LOT of time.
