The human condition is not something many of us ponder until something goes wrong upstairs. Whether it be within our own psyche or that of a loved one mental illness can be a black hole of unknown dimensions adversely effecting lives. Things like anxiety and depression are often frightening due to their impact upon relatively unexplored realms. Our minds are vast repositories of memories, thoughts, feelings, and sensations (Florey, 2021). When things go wrong in our lives, we can slip into a scary world of dark shadows seemingly immune to the warmth of the sun. Beyond Blue reports that anxiety is the most common mental health issue in Australia, with one in four experiencing it at some point in their lives. Therefore, the idea that these frightening states can be influenced by the trillions of tiny creatures inhabiting our gut is immediately arresting and thought provoking.
