That is the story of my life. And we, my friend are certainly not anywhere close to being alone in that. I'm sorry that it's so bad though. Depression is horribly draining.
I have narcolepsy. Which basically means my entire life is one long struggle to stay awake. So yes, I understand where you're coming from with the sleep thing.

But the sadness and the not wanting to do anything...it can get better. For me personally, I am a complete mess if I'm not on strong medication. Are you on any medications, or do you have a T? Do you have the diagnosis of depression at all?
