What door?

So, I'm a teacher in a small town, in a southern, "red" state. I grew up in the Southern Baptist Church. I became a Christian when I was seven. I was at the church just about every time the doors were open. I was in children's choir and GA's (girls in action), later youth choir, which enabled me to go on several mission trips. I went to a small Baptist college, and am still an active member at a Baptist church (although not a Southern Baptist one). My faith is very important to me, and so is my church. It would break my heart to leave my church. I guess for most people this wouldn't be a problem.

The problem for me? I've come to the conclusion in the past year that not only am I not that attracted to men, but I am very attracted to women. I am not straight. I am a lesbian... and only four people in this world know, and they are all either gay, lesbian, or bi. 

While I know that God made me the way I am, I am afraid of rejection, disappointment, isolation, loosing friends, and possibly even loosing my job if I came out about my sexual orientation. I don't feel like I have the courage to be a pioneer in this arena, at least at this time, but I'm praying for change.

As of right now, I have no plans to even look for the door of the closet, much less come out of it.
