Your grandmother can ask the court to terminate her guardianship and give it to the family friends, but that still requires a hearing. It's not difficult, I'm just not clear of grandma is in agreement with your plans, or able to return to court. If she is you can get the forms online. Good luck to you!
You should consider petitioning the court to be declared an emancipated minor. However, if you are only 8 months away from turning 18 that seems hardly worth it. Maybe you can go to your grandma and ask her if she will let you live with the family friends; she might say "yes."
