The quarterlife crisis is a term applied to the period of life
immediately following the major changes of adolescence, usually
ranging from ages 21 - 29. The term is named by analogy with
mid-life crisis. It is now recognized by many therapists and
professionals in the mental health field.
Characteristics of quarter-life crisis include:
feeling "not good enough" because one can't find a job that is at
one's academic/intellectual level
frustration with relationships, the working world, and finding a
suitable job or career
confusion of identity
insecurity regarding the near future
insecurity regarding present accomplishments
re-evaluation of close interpersonal relationships
disappointment with one's job
nostalgia for university, college, or high school life
tendency to hold stronger opinions
boredom with social interactions
financially-rooted stress
loneliness
desire to have children
a sense that everyone is, somehow, doing better than you
