Feeling "blah"

I attended a funeral yesterday. It was the second funeral and third death by cancer in the month of July alone. I've been feeling lethargic and out of it, just lying around reading, having not much energy to do much else. A part of life, I know, but I wish I could just "snap out of it" - I miss being my normal self! Ah well, as they say, "This too shall pass."
