OP- big hug. This is very frustrating and scary I’m sure.
You need to separate out the things over which you have zero control (how Florida determines residency for example) from the things you can control (like whether to take classes or try to work full time this summer). I know it feels like the world is out to get you, but that’s what bureaucracies are about- a general rule which covers most situations, but not necessarily yours at this particular time. There’s no point in getting upset- that won’t change the rules on residency and is only going to aggravate you.
You can still take a “Gap year” even though it’s coming a year late. You need to sit your parents down and explain that even though they think you need to be in college, your finances are going to prevent you from getting a degree in a reasonable period of time… and so you are taking a break in order to make sure that you qualify for in-state tuition, AND to give yourself a financial cushion once you go back to college.
