I need advice on how to lose weight?

So you will have to sit down with your parents and tell them that you understand that they work, and would like to start cooking your own meals so that you can eat healthier. Ask them to take you grocery shopping so that you can help decide what goes in the pantry. You can also try things like lean cuisines, or something like that if you really don't want to cook, but make sure you talk to your parents. I am sure that they want you to be healthy, just like you claim to. only you can change what goes into your body, and how much you excercise. You can run ten miles a day but if you are taking in more calories than you are burning, you wont lose anything. Good luck.
