A life coach is not a psychiatrist, psychologist or therapist of any kind that provides treatment for mental health issues such as depression, substance abuse or any other related issues. Life coaches are trained to facilitate your growth and transformation through specific tools, processes and practices. These help you evaluate your mindset and identify and overcome the obstacles that you are struggling with. Please seek out a trained mental health practitioner if you feel you need help with a serious problem.
If a client is working with a psychologist or counsellor, they may also work with a life coach in conjunction. Each of these focus on very specific dimensions of the person and can actually work quite well together for the client.
Life coaches do not dispense or prescribe medication.
