Journaling is an effective way to process our emotions
This is especially true if we take the opportunity to keep the journal private (for our eyes only) so we feel safe to share our darkest feelings and thoughts. It is only by examining them that we can understand them and ourselves and ultimately accept and love ourselves.
Using idea frameworks such as the Idea Compass, we can think about and understand where emotions come from and what they could potentially lead to.
The idea of being able to share your inner thoughts is very similar to the goals of psychotherapy.
