One of the many things I wish to discuss in great detail on this blog (in fact, it is one of the core missions) is how journaling and any writing for that matter can help one become mindful of whatever mental illness they may have or even for the average reader who needs to work on confronting emotions and thoughts of any kind.
I found a post about a how a young lady uses journaling to cope with Post Traumatic Stress Disorder (PTSD). This link is actually to a guest post by a blogger who is visiting the site that you will be directed to. It is a good, resourceful read. I hope you get something out of it.
