Hаrriet indicаtes thаt she has suffered frоm these symptоms at least seven times in the past three years when she has what she calls her episоdes. “When I get this way, I am depressed every day and all day. There is nothing I enjoy at all, even stuff I always have fun doing. I lose weight, because there is nothing that I want to eat. I just drink water and eat ice, but it is because everything is unappealing. I can’t sleep and wander around the house cleaning things that I know are clean. But during the day, I just can’t get up. I feel so very heavy, like there are weights on my feet. I am so tired and fatigued when these things come on me. I also have such a feeling of worthlessness and guilt, as if I am responsible for everything in the world that is wrong. I can’t concentrate or come to conclusions. And although I would never kill myself, I sometimes wonder why I go on when I have these episodes. It seems so pointless.” Harriet meets the criteria for what?
