Bad Sleeping Pattern

I do not know how this happened, but I am somehow back on a nocturnal sleep pattern. I recall something over a week ago, where I had to get up at 7 am, and then somehow that has slipped now to being awake during the night and greeting the sun from the wrong side again. I can not stand this pattern, I feel like I am so far off of where I should be, and emotionally I do not handle being awake on this side of things very well. I am awake now and I know its night and it feels like night, like I should be calming down and preparing for bed, even though I just woke up, but I know that if I go to bed now, I will not sleep at all, I will just end up irritated and more awake than I am right now.
I suppose I could actually try to get all of my tasks for the week completed and try to stay awake until the proper time tomorrow evening, but that will be difficult. I do not easily function for 24 hours at a time, but I suspect that waking up when I did will make that a little easier, since I would theoretically only need about 20 hours of being awake to get started back on the right pattern, which would be a big help.
