Everyone has a distinct personality. A combination of thoughts, emotions and behaviours that makes each of us unique. At some point, however, people can be influenced by challenges they face in their daily lives. As a result, it can become increasingly difficult to respond to these challenges. Personality disorder is a mental illness which causes an individual to develop rigid patterns of behaviour. It affects an individual’s perception and reaction to different situations. These difficulties can result in severe mental health issues including depression. Seeking a consultation with an expert is very important, as it can help identify the causes of the disorder and offer suitable treatments. If you are in need of counselling, please reach out to us. Our therapists in Thunder Bay offer the necessary help and support someone with a personality disorder needs. Please call us to book an appointment.

Most mental disorders begin in teenage years to early adulthood. Quite often, an individual suffering from a mental illness is unaware of it, however people around them notice changes. Many factors may affect your personality such as:

The symptoms of personality disorder vary from person to person depending on the cause. Personality disorder is categorized into two types, mild and severe. This disorder can be identified by work, relationships and impulsive patterns of an individual. The symptoms of personality disorder are as follows:


  • Anti-social behaviour

  • Feeling of disassociation

  • Feeling of negligence and emptiness

  • Frequent anger and anxiety

  • Impulsive behaviour
