Halls of the Dark Muse

I do not know what happend. I thought the day had gone rather well really for the most part. Nothing occured, there were no real problems or misfortunes, I had all in all enjoyed myself during the day, nothing fancy or speical really happend, but nonetheless things went well enough. But then for no particuarly reason that I can name, I sank down into oblivion. Nothing I can see really triggered it or stired it up, it just fell upon me quite suddenly. I do not know if I would truly say I was depressed at the moment, but I feel a certain dark anxiety upon me but perhaps this is the mere price to pay, for I fear at times my muse is as manic as I am and has mood swings all of its own making which do have the tendency to afflect me at such moments. I wonder if things would work better, or worse, if our mood swings were in fact in tuned with each other. So I can only wait for it to pass.
