Say: "Mom, dad, I wanna move out!"
But really: You must have reasons for that decision.
You probably have a plan about how to pay your own home. You probably have other reasons, too. Maybe you think that you'd get along better and with less trouble if you had some distance between you and your parents?
Whatever it is that makes you want to move out, you should discuss it with them. Tell them you've been observing/experiencing these problems or disharmonies. Tell them what you'd want your life to be like. And then say that you think you could afford your own place and that you think it would be easier for everyone if you tried moving out. Ask them what they think about that. Then listen to them. Consider their arguments. Maybe they'll make an alternative offer. Maybe they actually think it's a good idea and offer you help doing so.
Wow that sounded like my gf a while back. Her situation is she didn't get along with her mom so the same thing kinda like you with a room to rent that had a small kitchen were she struck a deal with with helping maintain the household from a friend of her dads. She received a very discounted rent, and still worked, and managed to do what she wanted without her mom on her back all the time. Sounds like you have a plan like she did...only difference is her mom was happy in a way she asserted her independence and left. Tell them your plans...details, job, school etc, show them your ready to be independent. Good luck.
I am an early graduate. I graduated in December. I would be renting the guest house from my bfs aunt and uncle and sharing it with his sister. The 1st reason I want to move out is there are wayyy to many people in my mom's house. There are 7 people and one dog in a 3 bedroom trailer. Second reason is me and my parents and one of my sisters don't get along
You can too move out at 17, I did and never looked back. But, and I do stress this, I had a plan and I did continue going to school. Is it that bad that you are considering moving out?
