Psychotherapists work with you over a longer period for more deep-seated issues. They help with psychological issues that have been built up throughout your life. You will probably have to go back to your childhood and discuss different life circumstances up until the present day to see how you were shaped and influenced. In doing so, you will get a better understanding of your feelings, actions, and thoughts. If there are past traumas or life experiences that are holding you back, then they will work with you to help sort them out. This can enable you to cope with your family break up and prepare for the future.
When looking to appoint a psychotherapist ensure they are a member of a recognised professional body such as BACP and you may want to consider their experience and specialisms.
