I woke up feeling highly sensitive to lights and sound. My thoughts aren't racing but I feel like I'm wide awake and exhausted at the same time. I'm hungry but I have no appetite. I have zero motivation to do anything, and I feel on the verge of tears for no reason. I'm feeling a lot of guilt and anxiety too, and I've been having nightmares all weekend.

How do episodes usually progress between mania and depression? Is it different for everyone? I was hypomanic a couple weeks ago, am I entering a depressed spell now?
