@Ewok2 I have definitely seen people recover with minimal or no journaling. It is possible.
However, the research on expressive writing shows that 2-3 sessions of 20 minutes can have an impact on your physical and mental health that lasts for years. I think a lot of people worry that they will have to journal every day for the rest of their lives, which is just not true for most people.
I have also seen people get very overwhelmed by the journaling exercises in a way that's counterproductive (particularly those with severe trauma, past sexual abuse, or PTSD). In these cases, the journaling CAN still be helpful, you just need to create a safe environment to do it in. I always recommend these people bring the exercises to a professional therapist and do it DURING a therapy session so that someone is there to help you process what came up.
I had the chance to interview John Evans, who is the co-author of "Expressive Writing: Words That Heal." His other co-author is Jamie Pennebaker, who has done the bulk of the research that's out there on expressive writing. Perhaps listening to the interview will help you figure out what to do next.
You can find it here.
One thing he said that stands out to me is "reluctant writers often have the most to gain by writing."
