Should I have to uproot myself and move between my parent's houses at their whim?

Sorry, but if you are living in your parents homes, and they are supporting you and you are a minor, then you have to do as they say. Don't like it, move out into your own place and support yourself. No excuses...it is quite doable if you put your mind to it and if you struggle a little and have to eat PB & J sandwitches and mac and cheese, so be it. I know some 17 yr olds that do just fine working part time and supporting themselves....They are young...it builds character.
