Blogging troubles

I am a horrible blogger. I know that. I couldn't really justify it or understand it until recently. I always assumed I was just too busy, and in truth, that is part of it. Working a new job in a new field doing something entirely foreign while also living in a hetic city and pursuing an MA in said field .... while, obviously it requires most of my mental and physical reserves. I realize lately, however, that there is more to it than this. Having grown up in an environment full of family secrets, I was taught that I shouldn't talk about what goes on at home. This is not something I've been conscious of before, but I realize now what a hindrance that is to blogging. I love the idea of blogging because it gives me a reason to write, an audience, and writing is my soul. I am always afraid, though, that I will write something I am forbidden to discuss, that my audience will be outraged and some horrible secrets will be spilled if I'm not careful. This leaves me with two alternatives: write about trivial things or write nothing. Obviously I have mostly chosen the latter. I think the time has come for a sea change in my thinking and my writing habits. Hopefully I am brave enough for this.
