I am sorry that you're having such a difficult time battling depression right now, Rose.

I can really relate. I have been battling depression ever since I was a little girl. Some times are worse than others, of course.
It sounds as though you're falling into one of those deep funks.
I take clonazepam to help me sleep at night, and ward off my PTSD nightmares. It typically does not help me fall asleep though.
Very gentle hugs to you. To all of us.
