Adulthood is the timeframe of growth when physical maturity is ending and specific biological, mental, cultural, individual characteristics, and various other developments concerned with getting older have taken place. Starting post-adolescence, this period of time is often grouped into categories by age, which is generally considered to be between the ages of 19 and 45.
Adulthood, much like adolescence, can be a turbulent and difficult transitional period for many young men and women. When young men and women struggle with transitioning into adulthood, they will sometimes self-medicate or distract themselves with negative behaviors such as drug/alcohol abuse. These behaviors can cause depression and eventually lead to fatal consequences. This is the reason that it is imperative for young adults to seek assistance if they find the transition into adulthood too difficult or overwhelming.
