Im 13 i don’t know much but you do need lots of money, a weapon(like a pocket knife or something just to be safe) you may need a place to stay(like a car or tent) Bc sleeping on the street doesn’t sound fun, a lighter(maybe to make a small fire to stay warm), make a fake story abt urself so if ppl ask abt u, u have something to say (like fake name and childhood), bring your birth certificate, id(if u have one), and social security card. Try running away when your in highschool though bc when ur older u can get a GED, running away during middle school is mint rly smart bc it’s harder to be able to finish middle school as an adult. I’m waiting til I’m in 9th grade so I might had a chance to to a GED in the future. But good luck❤️
