Yup it's just you, sorry mate.
When I was suffering badly with depression, or perhaps successfully in qualificational terms, as soon as I awoke and became conscious of my surroundings, the depression would descend. I hadn't even had time to consider any individual problems, but the depression arrived en masse in a sort of, "Hello, remember us?", way. For a brief second everything was ok, and then wallop!
It's a chemical reaction of course but it's also reliant on our sub conscience and what we have lurking there ready to wake us up with a, "Come on we've got a busy day of panicking to get on with. Only I'm not going to tell you why. Muhahaha". Etc. etc.
I don't know, is that any help or am I just blithering today?
