Finally, Hi Ellie, the purpose of journaling/free writing is to allow otherwise repressed emotions to surface into consciousness, in doing so, you can develop a greater insight about yourself. Particularly any emotional themes that may repeatedly surface. Once you've homed into this skill, these emotions which bring you turmoil will be in your awareness and serve no purpose. TMS is a process and you have to work through the negative emotions as well as enforcing positive beliefs. They both go hand in hand. Lastly, you should only be spending a minimal time on journaling/negative writing. Best regards
