I don't have physical fatigue so much as a persistent feeling of not having slept enough.
The desire to feel *something* is almost like an unpleasant excitement, but it's not quite the same as anxiety. At its heaviest it's still enough to make me feel a little bit sick though.
Ah, feelings of being a failure, good to see you again for the umpteenth time this week.
Just started the week and already got it, I fucking hate this
This might not applicable, but personally, my outlook each day has changed quite a bit since I adopted a new but very strange sleep schedule.
Somehow, out of the confused cycle of long drives, weird naps, and degenerate binges that characterized my winter break between semesters emerged a new pattern where I go to sleep at 7-9PM and wake up at 2-3AM. Several hours before dawn in the frozen dead of winter I'm somehow wide awake (without coffee) doing things I would normally put off indefinitely, while previously 2-3AM was typically the time that I would be going to sleep after having gotten little done. I think what happened is I started staying up so late into the open daylight that the advancing cycle wrapped around and approached a normal time to sleep from behind, and it ended up being anchored by my tendency to eat only a light breakfast and a large dinner each day, knocking me into a food coma at a time that happened to line up with the shifting cycle.
You, hypothetical sad-thread reader, may rightly ask, "How is this mindless patter relevant, and if it is, would you kindly get to the point?" and to this I might reply that this experience with sleep has genuinely opened my eyes (sorry) about how important rest is to one's outlook and functioning, to the point of being a major psychological factor. Over the last month or so, on fewer hours of sleep I've felt much more inured toward each day, despite having never considered myself a "morning person" and in fact having had a particular loathing for mornings for all my life. The conclusion I've reached is that natural "morning people" probably don't exist (if even I could stumble so haphazardly into becoming one) and that anybody wishing to enjoy the benefits of an early schedule shouldn't be put off by the idea that any special inclination whatsoever is required. As obvious as it is that good sleep is important, I never really cared about it until having actually experienced it and found that it actually does tend to put everything in a more positive light.
