YC accepts people without a specific idea for the very reason that the people they accept have lots of good ideas. Have you done a startup before? I think you'll find that there are 100 little decision points where you need to make the right choice, and that process is far more important than the initial idea. Even though I can be uneasy to share ideas, like you, I've always found that I've learned the most from sharing my ideas with super smart guys. The things I get back from them have saved me years of time.
