Afraid of Blogging

I am afraid of blogging. I have written a post almost every day, but when it comes time to hit the publish button I instead save it to draft. I am not sure why. The topics range from my desire to have a child to my recent visit with my dad. The topics are diverse, the grammar usually poor, the spelling checked and rechecked, but one thing remains constant, each post is very revealing.
In real life I seem to be an extroverted person who leaves no thought unexpressed, but in truth I am intensely private, someone who is comfortable alone. My home is not open to those who stop by uninvited, something unheard of in the friendly South. We don't entertain, instead we spend our time at home alone. But my posts are full of my thoughts, like this one. They say way too much about me. And I feel vulnerable and exposed, even in cyberspace, with a readership of two, or three.
I started blogging so that I could document our journey as we try to have a child but instead it feels as if every word I write exposes some deep and needy part of me that is better left hidden. It is strange, Helen of Everyday Stranger, a blog that I love and read religiously sent me a lovely email about writing about her twins and how she didn't want that to be painful for me. Interestingly enough, that has never been painful for me. I always thought that it was because I have had children, so I didn't feel entitled to the angst of those women who have never had a child. It is recently that have allowed myself to dream again, to see a baby and turn to my husband and say, "I want one of those".
Please forgive the misspelled words, any grammar errors, etc., because if I don't publish now, this will join all the other drafts.
