Why is my anxiety always unbearable when i wake but it gets better in the evening?

Cortisol spike in am: Dear Jeremy during the night many chemicals can build up in your system. Although many people have too little cortisol in the morning, making them sluggish, you may be producing too much, or having a spike, before waking. This can make you feel anxious or revved up. Also, your blood sugar may be low after fasting during sleep.
