sugahorse! Waking up via anxiety sucks (been doing that for quite awhile now too). Everything pounding away, yet still tired, take the anti-anxiety and the panic mellows and tired remains -- and then we start the day! Autopiloting to a job that is feeling just too much. Yup. Empathy and hugs to you...
Yup, this too. Is sleeping a lot something you tend to do when you are down? This is my tendency, even when I'm not physically tired, but like you say, emotionally exhausted.... maybe it just feels like there is less of the day to deal with, being asleep. But the anxiety issue is getting in the way of this... coping mechanism(?) Which is additionally confounding. Is that what is happening for you too, by chance?

(Is there any way to get on a cancellation list --or are you already?-- with the pdoc?)
