I have found that sometimes just the simple act of naming and recognizing an emotional state can be enough to move us out of that state. So, for instance, you may spend an entire day with some vague sense that something is wrong. You might spend some time brainstorming bad things that happened or simply feel confused and upset by the unwanted feeling. It might bother you all day and possibly even ruin events or projects that would otherwise be fun.
Sometimes, if you are lucky, it may turn out that you are simply having a feeling that you haven't named yet. It could be a sense of loneliness, guilt, or fear that once named will release your body to enjoy your day.
