Counselling tends to be a therapy of shorter duration, looking at day to day issues and choices being faced.
You can use it as a problem solving process, to gain support for certain issues you may be facing at a certain time in your life, or perhaps you may wish to look at issues of communication.
During your therapy you may find yourself wishing to further explore aspects of your counselling in more depth by taking a more psychotherapy based approach. Or you may find the results you hope to achieve from counselling changing. This can be discussed with your therapist at any time during your counselling.
