What, more specifically, do you feel powerlessness about? You said the "forces underlying your day-to-day existence," but what does that normally entail? What do you do more specifically to try to gain more power? How you ever tried simply acknowledging and embracing powerlessness?
Usually the powerlessnes comes from societal expectations and my unwillingness to break them, or my reliance on other people; e.g. having to stay in school and get good grades, or not being able to make someone like me (respectively). So a lot of times I try to counter this explicitly, like when I sought leadership of our high school government and then set it up in such a way as to be a de facto dictator. But more pervasively, I also tend to do favors for people or act kindly to them not purely on the merit of those actions, but also to establish a sort of personal debt that I can then invoke in situations where I feel powerless. So it becomes like a safety net. I've occasionally tried embracing powerlessness, but something deep within me just can't stand it. If I can do something to improve my situation I feel that I must, and if there's nothing I can do, I feel absolutely suffocated.
