Free write your feelings and disappointments on a piece of paper or on a computer without erasing or correcting your words. Simply keep writing without stopping to think or re-read your work. Let your emotions flow onto the page (or screen) without restriction. Print the page, if typed. Then fold the page, place it into an envelope and seal the envelope. A study from the Rotman School of Management suggests that the physical act of enclosing materials from a bad or disappointing experience helps a person to overcome negative feelings and achieve a sense of closure.
Start a diary or journal to record your disappointment. Write honestly about your feelings to give positive expression to inner turmoil. Reflect on how disappointment may become an opportunity for personal growth. Record your goals and hopes to become stronger. Over time, record your progress or struggles to achieve these goals.
Experiment with fiction as a genre of expression. Write poems, a short story or play that invoke themes of disappointment or heartache. Fiction is a creative way to channel negative energies. Use your experience to write narratives that deal frankly with themes with gravity.
Forgive yourself for any feelings of guilt. Elizabeth Gilbert, author of "Eat, Pray, Love" explains that writing "after that heartache of disappointment doesn't take only discipline, but also self-forgiveness." When you forgive yourself, you rid yourself of ill feelings that may prevent you from expressing your emotions in a positive, therapeutic medium, such as writing.
