Teenagers don't often get along with their parents, so the media tells us. And often, it's true. Being a teenager is an awkward period. You are assuming greater responsibilities and gaining more independence, but at the same time are still utterly dependent on your parents for some things. And that dynamic leads to some friction between parent and child.
As you prepare for college, there needs to be some sort of conversation about new boundaries and the amount of parental control you're okay with. This is especially important if you're living at home for college. You are more of an adult now and there is a new set of expectations for you. College is something your parents can't really help you with and shouldn't be the ones pushing you. You should be pushing yourself. With that needs to come an understanding from the parents: We will treat you like more of an adult because we expect you to act like one.
It's a delicate balance to maintain. Your parents will probably be helping you pay for college. Or letting you live at home. Or just playing the "we gave you life" card. Anyway you play it, you can't be completely on your own and you have to recognize that. If you and your parents can come to a consensus about the changes in your relationship, life will be better.
