Check the criteria for instate establishment. In most states, it’s that you have resided in the state for 12 months prior to your enrollment. If you left Florida…the time you were away would not count in that 12 months.
As a 24 year old, I believe you would be establishing your own residency in Florida for both admissions and financial aid purposes. So YOU would need to reside in FL for 12 months prior to your enrollment there.
It seems to me that you are not a resident of Florida at this time…you are a resident of Panama.
