Megan, I forget how old you are, but I am assuming that you are pretty young.
You have some choices to make. First you must decide to turn your dream of being on Broadway into a GOAL of being on Broadway. Then you can start taking the steps to help you reach your goal. Be sure that you plot a course with stepping stones close enough that you can step from one to another and not have to either take a huge flying leap and land safely or fall to your death.
Sounds like finding the name of a voice teacher is a step. Have you actually called her yet? That would be another step in the right direction. What about setting up an appointment to see the Voice Teacher? That is yet another step.... and all of those steps are well within your ability.
GO FOR IT!!! AND GOOD LUCK.
....and keep us posted on your step by step progress!
