Kev, I know what you mean. Blogs, are inadequate confidants, therapists, or even diaries. But that can be a good thing, if it leads to a way to consider the issue sans details on the blog. Which might give a better perspective, though it fails to satisfy the need to just blurt.
I’m even wary of discussing my mood or extra-curricular activities for fear of work-related analysis. This leads to the need for a dark blog.
Have fun in Dublin. It’s great there.
