How Can I Write, What I Don't Know How To Say

I've learned a whole lot regarding self esteem. I know that I have lots to share with other girls and women out there. The problem is that whenever I try to sit down and break apart what I want to write about, I always end up in the same place… a blank screen. I'd like to tell them how I grew up feeling inadequate and at times wondered if I really was meant to be. Just be. Be alive, be in the family that I was born into, and just be as a being. I want to share about each and every time I was a new girl in school. The story behind me having to be in 11 grade schools. I want to let folks know that they're not the only ones with that gut feeling, that awful feeling you get when you feel that all eyes are on you. But then my mind goes blank. All of the experiences that I had that have shaped me into the woman I am today, simply disappear from my mind.
I'd hate to have someone go through half of the low self esteem situations and experiences that I went through truly believing that they are the only ones in the world that can possibly feel that way.
The problem is that if there's something I know about is feeling inferior and intensely afraid that you will be ridiculed because of how you look or the way you speak. So why am I having such a hard time gathering my thoughts together? Am I really meant to write this story? The story of an ordinary person like everyone else who can help others by retelling her stories and the lessons learned?

Here's the first day of my journey to write the most important story of my life. The story of how I overcame the fear of not being liked. How Can I Write, What I Don't Know How To Say
