Egads, feeling unbelievably lazy and not a little bit pessimistic about life

Nothing bad has happened in particular. I just feel myself to be pessimistic about life and all the things in it. This feeling, unsurprisingly, is not conducive to productivity. Nor to the taking out of the zillions of cardboard boxes that are everywhere in my house. Someday, I am sure, I feel more optimistic, but that day isn't today. Which is a shame, because the weather is amazing. I had a party yesterday--which was a great time!--but now I feel worn out and wish I could just be alone all day. However, I threw the party because I was feeling off-kilter from a whole week of being by myself! Wish life didn't consist mostly of this bouncing back and forth.
