You just described me!

I woke up early, went to work and was on top of the world when I came back, despite the fact that I clean toilets. I went to get an extra hour in bed and woke up as the complete opposite. I went back to bed (again) but the switch obviously doesn't work the other way. Another depressed day.

Developed paranoia towards the late afternoon.

So... you're not alone

You could show your doc what you wrote in your post. I think it's extremely eloquent.
