I just feel so tired I can't do anything. If I don't set my alarm clock, I spend a couple of hours trapped in this gross in-between space that isn't quite being awake and isn't quite being asleep. If I do set my alarm clock and get up, I feel tired throughout the day. It doesn't matter if I get three hours of sleep or if I get ten: I get up, feel fine, have breakfast, and then want to go back to bed a couple of hours later. So what am I supposed to do about that?
Perhaps it's all some strange permutation of mourning. But in that case, I would rather be sad and then have energy instead of feeling nothing and having my energy sapped.
