I've been thinking about you op and I'm glad I've refound your thread..
I have the very same symptoms - aka depression. I simply cannot get going in the morning. Drives me nuts! The very last thing it is is laziness. Ime the more I chide and beat myself up the less I can do.
For me it's like the brain is fine but the motor's gone. That's the best way I can describe it. I simply can't function normally.
A few tips that help me: make the whole morning routine easier/shorter/less onerous. You don't have to shower every day, you can wash. You could try immediately getting washed/showered and dressed first thing when you go to the loo in the morning eg leave your ADs upstairs, take them when you wake up, go for a wee and get in the shower /wash. THEN go downstairs. This transforms my day bcs I've launched without realising it.
Appts in the morning are good but beware, I often get to them dragged through a hedge backwards not brilliantly ready. But at least I'm there, up and out, doing something. In general though I make appts in the pm to make sure I'm calm and ready.
As a pp says, it's the thought of it all that puts me off and I simply can't do it. I think this is where routine is our friend : plan it the day before = a little list (ADs, wee, shower, makeup, dressed, breakfast) and don't think about it, just do it.
At the moment I manage to get going half the time. Maybe more like a third. But it's better than nothing eh. I'm also working with some mental health charities to work through getting going on some pressing issues - have a look in your area.
