agreement that the earlier crises tend to be more forward-looking and are characterized by anxiety and confusion about the path in life one wants to follow. The later crises, on the other hand, are more backward-looking, often in the form of guilt and regrets, while also concerned with the problem of one's own mortality. These different crises can affect each other in various ways. For example, if an earlier crisis was not properly resolved, later crises may impose additional difficulties for the affected. But even if an earlier crisis was fully resolved, this does not guarantee that later crises will be successfully resolved or avoided altogether. Another approach distinguishes existential crises based on their intensity. Some theorists use the terms existential vacuum and existential neurosis to refer to different degrees of existential crisis. On this view, an existential vacuum is a rather common phenomenon characterized by the frequent recurrence of subjective states like boredom, apathy, and emptiness. Some people experience this only in their free time but are otherwise not troubled by it. The term "Sunday neurosis" is often used in this context. An existential vacuum becomes an existential neurosis if it is paired with overt clinical neurotic symptoms, such as depression or alcoholism.

This concerns specifically the relation to one's family and often leads to spending more time with one's peers instead. Various rebellious and anti-social behavior seen sometimes in this developmental stage, like stealing or trespassing, may be interpreted as attempts to achieve independence. It can also give rise to a new type of conformity concerning, for example, how the teenager dresses or behaves. This conformity tends to be not in relation to one's family or public standards but to one's peer group or adored celebrities. But this may be seen as a temporary step in order to distance oneself from previously accepted standards with later steps emphasizing one's independence also from one's peer group and celebrity influences. In order to resolve the early teenage crisis, it is important that meaning and purpose are found in one's new identity since independence without it can result in the feeling of being lost and may lead to depression. Quarter-life, sophomore, and adult The term "quarter-life crisis" is often used to refer to existential crises occurring in
