Loneliness affects everyone at some point. Loneliness is a normal signal that informs us that our social needs are unmet. Loneliness is subjective and can occur even if we are not alone. For some people, it may be a transient feeling and for others, it may more persistent. Current research indicates that loneliness leads to poorer mental health and physical health outcomes. 

People who are lonely are more likely to die earlier and report more co-morbid health problems. Many people with mental health difficulties also experience loneliness.
