I might be reading it wrong here, but it sounds like Miami is a Uranus line, for you? It sounds like you value freedom and not being told what to do! You do seem like the type to like that type of energy, so I do think that you might like it there! It also depends on your natal chart, and the house, and sign, that the city falls into your chart, and on the city's chart, too!
I'm being nice here, but maybe before you move, you should go get help from a therapist? Personally, I think you might need help!
If you're going to turn over a new leaf, why not start your life in a new place, with a clear mind? You'll have a better reputation there, and make more friends!
You might cuss me out with your reply to me, but I get it, you're a Leo, it's hard for you to admit that you might need a little push! You might hate me, or cuss me out for giving you advice, but I'm speaking from experience, I had severe CPTSD as a child, and until I got help, people were going to put up boundaries against me!
Good luck!
