Sometimes with my journaling I'll write out my issues and feelings but other stuff will come out too, like subconsciously, and it helps me a whole lot. Like I'll feel something becauyse of a certain situation so I'll write it and then go 'oh this reminds me of when I was a kid when my mother..' and write that. It also just helps me express my feelings, and sometimes I write third-person narratives to calm me down in my journal.
