I Need A Really Big Rock

Lately all I've wanted is to crawl up under a rock and pretend the rest of the world doesn't exist. This is a little disconcerting because for the past several months I have been fairly happy and content with myself and life in general. Granted I have my ups and downs like anyone, but I rebound pretty quickly (at least that's what I think, although Kay (my co-worker) may say differently, since she catches the biggest part of my bad moods). But for the past few days I have been seriously unhappy and discontent with life. I alternate between feeling like nobody cares, to not wanting to talk to anyone. I had forgotten how it feels to want to cry all the time, because it had been a really long time since I've cried because I was sad, until the past few days (during which I've managed to make up for lost time). I feel like when I smile it's pasted on, and my laughter is fake and short-lived. I am moving through my day on auto-pilot, not because I am so busy (although I should be), but because I know that I don't have a choice but to get up, go to work, go to school and go home (at which point I firmly park my big butt on the couch and don't move until I convince myself to move to the bedroom to fall into a restless sleep). Needless to say, I really, really, really hate feeling this way!
