Speak to your parents, arrange a time period of when to use it and when to do something else. I had this problem once, I leveled it out with reading books and before I knew it the internet popped back on.
If you yourself think you have an addiction then maybe you should ask them to take it down for a bit so you can cool down and focus on other things in life. Remember school is always more important than games. Video games will always be there, school will not. You have plenty of time for games when you are older and have a job.
EDIT: Your banned but I'll leave this up as many other people that have this problem with their parents.
