I, too, am very worried about anyone reading my journals so I edit myself and don't write my most private stuff. Even though I live alone and my words would only be read after my death it's hard to be honest on paper with that fear. In the winter when I was so alone and broken and needed to express the things that were so troubling and ultra private I wrote it out in another journal and kept it for a few days, reread it and got what I felt I needed from it as a source of acknowledgment, then burned the pages. Safe. I do find collecting my thoughts on paper to be very helpful but mostly boring to anyone who would read it. I'm not so worried about anyone reading my edited version.
