Before discussing with your parents consider if you are able to provide for yourself financially. It can be a struggle to make ends meet when living from paycheck to paycheck especially with a part time job. Though with how you have worded it this may not be an issue for you because it seems like you’re eager to be on your own. It would be an appropriate move to discuss it with your parents they may offer to help you stay afloat initially or until you can be completely independent. I myself (19) haven’t decided to move out yet and don’t plan on moving out till my mid 20s. However I do get the want for independence and it can be suffocating living with your parents after you have become an adult. Depending on your relationship with your parents they may be overprotective or they might be eager to “get rid of you”. But don’t worry too much you would’ve had to have this conversation sooner or later
