I don’t see a downside to transferring if your family will offer support. Family support can help depressed or anxious students (if they’re able/willing to provide support - you know them, will they help or make things worse?). In addition, you may be experiencing culture shock’s second “bottom” in the W (it’s real and it makes you question everything).
Take a leave of absence from your current college. ← very important administratively.
Over the summer, take one science class and one gen ed per session (if there’s just one summer session, take one science class only) at one of the CCs in Orlando, they should be relatively cheap. See if you enjoy your classes while living with your relatives. Find a job (indicate you’ll be staying year-round). Apply to UCF by July 1st. Or, perhaps, take it easy for one more semester: continue at the CC for the Fall, repair your GPA, then transfer (apply by October 1 for Spring acceptance to UCF).
