Mental health involves the presence of positive characteristics such as: being able to cope with life's challenges, staying in control of emotions and behaviors, managing stress, building strong, healthy relationships, and recovering from setbacks.(source: Mentalhealth.gov)
While effort is required to build and maintain physical health, the same is true for mental and emotional health. Improving mental/emotional health can benefit all aspects of life, including boosting mood, building resilience, increasing learning, and adding to the overall enjoyment of life.

What is Mental Illness?

A mental health concern becomes a mental illness when ongoing signs and symptoms cause frequent stress and affect your ability to function. A mental illness can make you miserable and can cause problems in your daily life, such as at school or work or in relationships. (source: Mayo Clinic)
According to NAMI (National Alliance on Mental Illness), trying to tell the difference between what expected behaviors are and what might be the signs of a mental illness isn't always easy. There's no easy test that can let someone know if there is mental illness or if actions and thoughts might be typical behaviors of a person or the result of a physical illness.
Each illness has its own symptoms, but common signs of mental illness in adults and adolescents can include the following:

• Excessive worrying or fear

• Feeling excessively sad or low

• Confused thinking or problems concentrating and learning

• Extreme mood changes, including uncontrollable “highs” or feelings of euphoria

• Prolonged or strong feelings of irritability or anger

• Avoiding friends and social activities

• Difficulties understanding or relating to other people

• Changes in sleeping habits or feeling tired and low energy

• Changes in eating habits such as increased hunger or lack of appetite

• Changes in sex drive

• Difficulty perceiving reality (delusions or hallucinations, in which a person experiences and senses things that don't exist in objective reality)

• Inability to perceive changes in one’s own feelings, behavior or personality (”lack of insight” or anosognosia)

• Abuse of substances like alcohol or drugs

• Multiple physical ailments without obvious causes (such as headaches, stomach aches, vague and ongoing “aches and pains”)

• Thinking about suicide

• Inability to carry out daily activities or handle daily problems and stress

• An intense fear of weight gain or concern with appearance (mostly in adolescents)

Mental health conditions can also begin to develop in young children. Because they’re still learning how to identify and talk about thoughts and emotions, their most obvious symptoms are behavioral. Symptoms in children may include the following:

• Changes in school performance

• Excessive worry or anxiety, for instance fighting to avoid bed or school

• Hyperactive behavior

• Frequent nightmares

• Frequent disobedience or aggression

• Frequent temper tantrums
