Most people who know me in real life know I'm INCREDIBLY mature for my age (saying I act 16, maybe 17).
Acting 16 or 17 doesn't qualify as incredibly mature.
On your other thread you alternated between the following careers: Real estate agent, nurse, McDonald's employee, barber, doctor, Disney employee...and several others, as I recall.
Of those jobs, the only ones you can do straight out of high school are McDonald's and Disney employee...neither of which will pay you the salary you are depending on to make ends meet. You're going to have to get by on a lot less...it can be done, but you have to be realistic about how you'll be living.
Maybe barber, if you take hair-cutting in high school.
I'd suggest using the time before you move to formulate some kind of realistic plan about how it is going to go when you do move, starting with the move itself.
If I were your mom, I'd tell you to figure out WHY you want to go to Florida. For a year to work for Disney, then on to college? Are you planning to stay there?
You're going to need 1st month's rent, plus security deposit (and possibly last month's rent, as well) and you're going to have to find someone willing to rent you an apartment. They'll want verification that you have a job! So, you'll need to have a job lined up. After all that, you have to think about furniture, etc.
And this is all just the beginning of the planning.
There's a lot for you to do, if you are serious.
What are your parents telling you?
