What should I do about moving?

To make it short and simple I’m planning on moving states to live with my friend because my family is emotionally abusive. I have to do it in secret because they dont want me moving there (I’ve already tried telling them) and i wanna leave as soon as tomorrow however i gotta go by plane but is it risky to buy a plane ticket that short of notice? Also i wanna leave cuz i can't stand my job anymore its too stressful at this point. So what should i do?
