If I was to run away where would be the best place to go?

Im 19 and in a downward spiral school wise and I don’t want to face my parents if i fail out. I don’t need people to tell me my idea is stupid or that my parents will love me regardless Im just looking at my options right now. Im just asking if live in Philadelphia from there where should I go? I also cant drive so Ill have to bus it there or hitch hike or something
