I can relate to this. Morning is my hardest time of day. I wake up with this sense of dread, what is this day going to bring. I also suffer nightmares that seem to be worse early in the morning. I wish I had some good advice for you. I just make myself get out of bed, shower, and go to work. Usually by mid-day I feel better.
I drink lots of coffee too, and do a lot of praying when I can concentrate. My added factor is that my migraine headace medicine makes it hard to get up in the morning. When I tried to taper off of it migraines headaches came. I can't function with migraines so I went back on the migraine medicine.
Best wishes
