So sorry to hear what you've been through. Stay strong.
To answer your question, I have felt more anxious in the mornings, yes.
I spoke with my doctor about it a few years ago and he explained that in the morning, our cortisol is highest. (Cortisol is the stress hormone produced by your body when you're stressed/anxious).
Paradoxically, though, anxiety produces cortisol....which produces anxiety...and then more cortisol.... see where this is going?
My doctor said the most important thing is to truly "accept" the anxiety rather than fighting them. When you truly can learn to do this (it isn't easy - but it can be done)- the morning anxiety should dissipate.
Another thing to note: After sleeping all night, our blood sugar is lower, too, which for some, can make people shaky. The word "Breakfast" literally means "breaking the fast". Eat breakfast. Very important.
*** On a personal note, here, I've noticed something: on the weekends, I don't set the alarm. I just get up when I open my eyes. I don't have the problem, then. Also, I noticed, during the week, with alarm set, if I wake up before it goes off, I notice that I feel pretty good. But, if I wait for that alarm, sometimes, I end up getting up and feeling anxious.
**** I wonder if listening to our own inner alarm clock (as long as it gets us up in time for work) is the way to go here? ( meaning, get up when you feel ready...you can still set that back up alarm in case you decide to fall back to sleep).
