I'm completely honest when I journal, which means I can write completely different thoughts or feelings to the next. I don't consciously censor, but I don't write about some topics, because some things I don't find journalling about them helpful. So my 'journal' isn't a complete narrative. There are often big things in my life that I just don't cover.
But it is misleading for me to talk about my 'journal' as if it's a single item. i have both a writing/reflecting general journal, but also add a lot to my daily diary, and I keep both. I have a few seperate books for journalling about particular topics, so that all my thoughts and memories about that topic are in one place, and can be destroyed seperately to the rest of my life.
Add to that, I journal in different formats. I keep 2 digital journals (seperate to my one here), as well as a therapy journal (a madhouse mix of different formats), a flash drive journal (with seperate file for pics, which is also a form of journal, and not all pics are relevant enough to get stored), an art diary, and a poetry journal.
I've been journalling at an ebb and flow rate since primary school. Different types of journalling serve different purposes for me. But if I had to amalgamate them all into one book, I would have to censor. I couldn't handle the thought of all those conflicting and painful and toxic things being in one place.
Mum knows I want my journals destroyed if I pass away, and I believe that she'd do that for me honestly. I don't really worry so much about other people reading them. I think maybe it's my DID, but I'd need to censor because I can't handle all the different parts of my life colliding. I need to keep them separate, and controlled. That, I think, is an odd form of censorship probably.
