This condition, which we also define as boredom, is a set of symptoms that last at least two weeks, affect the person's daily work and life and cause significant distress, such as a general lack of interest, inability to enjoy anything, withdrawal, loss of motivation, deterioration in appetite and sleep (may increase or decrease), fatigue, weakness, lack of concentration, feelings of guilt, helplessness, inadequacy and failure, and negative thoughts about oneself. The severity of complaints may vary during the day. In severe cases, these symptoms may be accompanied by thoughts of death and hallucinations.

Although it is most common in the 40s, it can affect patients of all ages, and the symptoms may vary depending on the patient's age. While irritability and anger are more pronounced in young patients, symptoms such as physical complaints and forgetfulness may be more prominent in older patients.

It is more common in women than men.

Depression is a treatable disease, and the effects of medications and psychotherapy have been proven in treatment. The support of the patient's relatives is also very important during the treatment process.
