Random clarity at late hours of the night?

I wake up severely depressed everyday and I feel it all day and night. But at a certain hour of the night around when I'm going to finally fall asleep, I get this relief, this random clarity from my depression and anxiety and I feel like everything is going to be ok. Sometimes I use that time to actually get some things done around the house. But then I go to sleep... And wake up in the same dark hole trying to climb out. Does anyone else have this happen??
