Writing my autobiograpgy about my life with aspergers?

I want to write an autobiography about my life someday and hopefully get it published. The problem is that Im only 19 and not famous. But I have big dreams and aspire to one day be a professional baseball player. Ive been dealt with many trials and tribulation throughout my life. These things range from severe depression,being suicidal,being a social outcast,growing up practically on my own, my parents getting divorced, the death of my uncle and other family members at a young age, a bad relationship with my parents, my middle school and high school life.

I also hold many deep secrets that not many people know about which includes having aspergers syndrome, which has crippled me in almost every aspect of life. I feel like if I wrote this I'd be able to portray a universal message to readers and in the process write a compelling story that could help people. I could potentially shed new light on whats it like to live with it on a daily basis.

How should I go about this? What would be the likelihood of the book making it big because not many authors out there have touched on the subject of aspergers, let alone lived with it. Also if it ever became big enough nationwide could my life be potentially made into a movie. I know the latter is highly unlikely but im just curious.

Recently I found out about John Robison and his book Look Me in the Eye. Unfortunately I havent gotten around to getting it yet, but I have every intention of reading it at some point.

The fact that aspergers has been touched upon by a few people wont discourage me in my pursuit of writing the story beacuse I truly believe that it needs to be told. Its such a debilitating syndrome that is very foreign to the general public, even psychologists still have a hard time grasping it.
