We often hear the term "mental health" used in reference to conditions such as depression, anxiety, post-traumatic stress disorder (PTSD) and schizophrenia. But really, "mental health" refers to our overall emotional, psychological and social well-being, both in and outside the context of named conditions, according to MentalHealth.gov, a resource curated by the U.S. government. 

Our mental health impacts how we think, feel and behave; it shapes how we perceive the world, make decisions and handle stress when it comes our way.
