I'm sorry, I don't know exactly which link you're referring to (I post too many, oops).
In your case, as a minor, it's probably going to be up to your parents to really push your school to meet your needs.
The ADA is the general law that covers your rights. The areas that are more specific to schools are Section 504 of the Rehabilitation Act of 1973 and Title II of the ADA. Also, IDEA and your IEP are important for you. More about these things can be found at this link (sorry, another link):
Section 504 and ADA Obligations of Public Schools | National Association of the Deaf
You are a brave and mature young lady for trying to advocate for yourself. Sometimes the fight for equal access is hard--you might have to be a pioneer in your school district.
Shel and others who work fulltime in the Deaf education can probably give you more "how to" information. Also, hearing parents of deaf children who have experienced similar frustrations might be able to give you and your parents some tips about how they resolved their problems with the schools.
As you get older, you will probably become more familiar with the ADA as it relates to college and job opportunities, and your rights in the medical and legal areas.
The ADA gives you the legal rights. Sometimes you still need to fight to get them applied to your situation. They aren't always automatically done for you (even if they should be).
Don't give up.
