Starting a Blog

OK, this is really scary. I have always loved writing, reading, anything with words. I started keeping a diary in 1st grade. I read the book Harriet the Spy and turned my diary into a notebook that I kept since I was 16. I still have the huge stack of notebooks and when my older daughter turned 15 or so, I pulled them out and read them. Good grief! I belonged in a psych ward! I can't believe how much of a basketcase I was then! My emotions were unbridled. I was depressed ALL the time. Somehow I just don't remember feeling all that horrible about my teenage years....and then it hit me. I only wrote about the bad times, the sad times, but in the good times, I shared those with others in person. So it was skewed. Anyway, fast forward to 2008. I am on facebook and read what one of my teenagers wrote on her status. Good grief! She belongs in a psych ward! What a basketcase! What kind of a mother am I? I didn't have a clue that she felt this way! Oh dear.....oh wait! It's just like my writing in my notebook back in the 70's. Only that was private. This is really really public. Hmmm.
Am I going to regret writing things so others can read them? Should I stay anonymous? Does anybody else feel kind of fearful about this like I do?
