i kno how u feel, well if u don't kno squat u might wanna start out by goin to a music store and buyin some begginer books for guitar. just ask someone there to help u and they'll get u wut u need. or u can take lessons if u don't want to teach urself. but if u already no how to play u can search online for greenday tabs or other bands. i'm new to this too, but good luck and welcome
