Anyway, you'll do great InshaAllah! My prayers and wishes will always be with you ukhti!! So work hard and leave everything else to Allah SWT, for He's the best ultimate decider!
Oh, ok, and NO, you're not almost 18, there's still almost half a year to it!
(sorry to burst your little bubble
) But all the kidding apart, MashAllah you being this dedicated to Islam at such an age is eye-watering! May Allah SWT help you and your family out in every step of your life and bless you with jewels of faith, health, smiles and prosperity in this life and in the life of the hereafter! Amen
