Moving to NYC

Hello , long story short. Leaving my city. Too many emotional issues lately and I need a fresh start somewhere. Visited NYC a few months ago and I fell in love with the city. Don’t worry I’m not a teenager who’s running away from home. I am a young adult running away from home, but anyway lol is there anyone in NYC that can help me out? What should I prepare for ( I plan on leaving in October-ish). Nothing is set in stone yet but I just know this is something I should do. Please any insight will help
