There are many different kinds of journaling.
Journaling in a diary ..where you write your feelings down and what happened in the day. You write inside it. And then there is art journaling… where you express your feelings with pictures and drawings that you smash together, creating an art journal. Art journaling and journaling are pretty much the same just in one way you express your feelings with words in in the other way you express them though art.
I love art journaling and you can see my sisters drawings at: http://www.sketchinginwonderland.blogspot.com. I love both to Art Journal and Journal because i both love to do art and write. If you just normal Journal don’t be worried what people might say because nobody (unless you let them) will see other then you, so rant and rave, but when your done don’t read it because you don’t want to get all scared, mad, or sad about what you just wrote again so calm down and read it at least 2 months after you wrote it:).
In art journaling you can let people see it without them knowing your feelings because you have art and not words ( maybe a few) but art which people do not know your secret way of art, your artsy thoughts. I hope this helped you decide what is your thing, Art journaling or journaling. You can do both, i do i rant and rave in my journal ( then hide it under lock and key) and then a put my secret feelings in art were nobody can truly know how I feel.
