We all tend to find that we fall into certain patterns of behaviour in our life. Often we tend to form the same types of relationships, or take on the same roles in work or family life.
For some people these patterns may be self-destructive, in that they often find themselves in the same types of problematic relationships, or that they keep on making the same mistakes. Other people may find it difficult to avoid doing things that they know are harmful, such as drinking too much, gambling beyond their financial limits, or getting on the wrong side of the law.
Usually these difficulties are related to underlying emotional problems which developed earlier in life. In therapy, such as Mentalisation Based Therapy, these problems can gradually be faced, and more helpful coping strategies developed.
