Lately at work if I’m trying to concentrate but then I hear the fan or someone talking I all of a sudden feel flustered to the point where I’m almost unable to perform my job. It even gets so bad to where if I was asked to set aside 10 pieces of paper that I would have to recount multiple times or even stop after pages and think I miscounted one. This makes work very hard and I was wondering if others share this problem and how they fixed it.
