Breakups can be heartbreaking and emotionally painful. We also need to understand that we need to accept our life circumstances and every moment create a more fulfilling life for ourselves. Holding on to the past or being excessively worried about the future ruins our present. If its been two years and u have been unable to move on i d suggest meet or consult a psychologist. It will help you formulate and re- view your goals in life and work on them.
