Hyped up is a good way to put it, like Anna said. My sleep is at its worst when I don't have a schedule to keep ... like now. When I had school and work, it was easier to keep to a schedule because there would be major consequences if I didn't. I had a few nights I had problems, but the majority of the time it was managable.
That time period between semesters, and those first few days back in class after a long holiday was difficult. I would be so relieved to be getting back to work, but nervous; my mind and nerves would not shut up. Plus, I'd always be worried, since every semester has a different schedule ... my routine would have to change every 4 months. The first week is always hardest getting used to a new routine. My short term memory is horrible -- copious lists need to be on the fridge, in my vehicle, on each notebook, in the bathroom ... I really depend on lists and schedules to keep me moving to the next thing to check off for that day. It is extra exhausting till I get used to it and can remember more because of repetition.
There are still major consequences (maybe even worse than before) now that I don't have a full schedule to follow except my own. I'm having a hard time finding anyone who will hire me. I'm waiting on a few possibilities, but till then, my days are spent holding on to every shred of sanity I have, and clinging on to any form of 'purpose' I can find. I'm not doing as well as I'd like.
I was doing well for a while, but I'm slipping into bad habits of staying up late and falling asleep when the sun comes up. I have a hard time falling asleep when I haven't been very productive during the day -- the night has less possible distractions so my mind and nerves are like one of those little yappy dogs.
My soul needs to have accomplished something worth while, or I ache with excessive energy that I haven't spent. I go out and even pick up trash along hiking trails, parks, creeks ... etc. Did a lot of house stuff like cleaned out the gutters, landscaping, those neglected chores we fall behind on when we are busy.
Sleep is much better when I can follow a well honed routine and have been productive and feel good about myself. Right now I'm slipping and just trying to hang on till those work possibilities come through.
