over-working

I am really crashing this evening. I've been pushing myself really hard lately, perhaps as a distraction. I was aware on some level that I was doing it, but couldn't seem to stop. My mom was planning a visit and I had somehow got it into my head that it was this weekend. It wasn't until the early hours of the day I thought she was arriving that I realized she was coming the next weekend. My mania is all catching up with me and I need some sleep.
