Psychotherapy is a treatment process to help people deal with psychological issues, such as depression, anxiety, and post traumatic stress disorder. When psychological issues start to get in the way of your ability to function, that is when you may want to consider psychotherapy to treat your issues and regain control of your life.
Psychoanalytic or psychodynamic psychotherapy draws on theories and practices of analytical psychology and psychoanalysis. It is a type of therapy that will encourage you to say whatever is going through your mind. This will help you become aware of hidden meanings or patterns in what you do or say that may be contributing to your problems.
Therapies such as Hypnotherapy and EMDR are forms of Psychotherapy.
