It's hard to say without knowing your age, but you might try a calm and reasonable discussion of a person's right to privacy, the process of learning independence and responsibility, and how a young person earns the trust of adults.
You can't learn to think for yourself, make good decisions, and take care of yourself if you never have a chance to do it, but it is best if those things come in gradual steps. Perhaps your parents would be willing to talk about those steps and when and how they should occur.
leave from home
Not
Then they could stay up all night alone and leave their homes without their parents.
You do drugs.
Rizal didn't want his parents to know that he will leave simply because he don't want them to be worried of him. And if they know that he will leave they will not permit him because they how how dangerous it is to live alone and away without someone regularly supporting of him financially.
16 is the age in New Zealand that you can leave school without the permission of your parents.
You can ask your friend to leave you alone by simply telling her you have a need to be alone sometimes or be with different people. If she does not take the hint then you have no option but to be honest with you.
To get on a airplane alone you must be 16 with ID and a passport. I am not sure if a passport would be issued to a 16 year old without a parents signature and some sort of letter or permission by the parent to leave the country.
If she is your EX girlfriend, the she is nothing to do with you any more, do as she asks LEAVE HER ALONE to make a new life without you.

First, you must know when it is time to say so. If you are too young to take care of yourself, they'll point and laugh. If not, tell them exactly that without throwing a tantrum. Just give them a reason to leave you alone and be sincere about it, giving gratitude of the fact they care so much to talk to you.
You should ask them nicely to please leaves you alone. If that doesn't work call their parents and say next time he won't leave me alone I am going to the police. Though make sure you do it in a firm voice.
