Post-traumatic stress disorder (PTSD) is a mental health condition that's triggered by a terrifying event — either experiencing it or witnessing it. Symptoms may include flashbacks, nightmares and severe anxiety, as well as uncontrollable thoughts about the event. Most people who go through traumatic events may have temporary difficulty adjusting and coping, but with time and good self-care, they usually get better. If the symptoms get worse, last for months or even years, and interfere with your day-to-day functioning, you may have PTSD. Getting effective treatment after PTSD symptoms develop can be critical to reduce symptoms and improve function.

A mental health disorder characterised by persistently depressed mood or loss of interest in activities, causing significant impairment in daily life. Possible causes include a combination of biological, psychological and social sources of distress. Increasingly, research suggests that these factors may cause changes in brain function, including altered activity of certain neural circuits in the brain. The persistent feeling of sadness or loss of interest that characterises major depression can lead to a range of behavioural and physical symptoms. These may include changes in sleep, appetite, energy level, concentration, daily behaviour or self-esteem. Depression can also be associated with thoughts of suicide. The mainstay of treatment is usually medication, talk therapy or a combination of the two. Increasingly, research suggests that these treatments may normalise brain changes associated with depression.

A mental health disorder characterised by feelings of worry, anxiety or fear that are strong enough to interfere with one's daily activities. Examples of anxiety disorders include panic attacks, obsessive-compulsive disorder and post-traumatic stress disorder. Symptoms include stress that's out of proportion to the impact of the event, inability to set aside a worry and restlessness. Treatment includes counselling or medication, including antidepressants.

Feelings of loss and grief can be experienced after we lose someone or something we care about like; the death of a loved one; loss of a relationship; loss of a pet; loss of a job; a change to your way of life; or loss of important possessions. The grief you experience in these instances is not an illness - it is a normal response to a life event that everyone must face at some point. It takes time to adjust and to learn to live our life without that person, thing or way of life.

Workplace stress is the harmful physical and emotional responses that can happen when there is a conflict between job demands on the employee and the amount of control an employee has over meeting these demands. In general, the combination of high demands in a job and a low amount of control over the situation can lead to stress. Stress in the workplace can have many origins or come from one single event. It can impact on both employees and employers alike. It is generally believed that some stress is okay (sometimes referred to as “challenge” or “positive stress”) but when stress occurs in amounts that you cannot handle, both mental and physical changes may occur.

Eating disorders are serious mental illnesses; they are not a lifestyle choice or a diet gone ‘too far’. They can harm a person's health, emotions, and relationships. There are several types of eating disorders. Common types of eating disorders are anorexia, bulimia, binge eating, and avoidant/restrictive food intake disorder (ARFID).

Chronic pain and ongoing health concerns can often affect every aspect of the individual’s life, including their relationships with others, employment, and ability to participate in normal activities. These life disturbances can cause psychological and emotional suffering. They often experience negative emotions such as a fear of being judged negatively, experience mental defeat, and have higher levels of shame and guilt than people who are healthy.

Compulsive gambling, also called gambling disorder, is the uncontrollable urge to keep gambling despite the toll it takes on your life. Gambling means that you're willing to risk something you value in the hope of getting something of even greater value. Gambling can stimulate the brain's reward system much like drugs or alcohol can, leading to addiction. If you have a problem with compulsive gambling, you may continually chase bets that lead to losses, hide your behavior, deplete savings, accumulate debt, or even resort to theft or fraud to support your addiction. Compulsive gambling is a serious condition that can destroy lives. Although treating compulsive gambling can be challenging, many people who struggle with compulsive gambling have found help through professional treatment.
