I'm pretty sure its an Am in the verse...? 
though I may be wrong, it seems to sound better open, not barred 

C Am x2 

C                     Am 
you can smoke by the water 
and leave your friends behind 
you can do what you wanna 
just close your eyes 

G                      F 
but you're holding on tight 
G             F 
it will be alright 
G               F 
its okay to let go 
     G         G 
you know 

you can leave if you need to 
you've just gotta stay still 
you speed up and you slow down 
thats just part of the thrill 

but you're holding on tight 
it will be alright 
its okay to let go 
you know 

Em                     G 
sometimes its a living hell 
head hurt and you don't feel well 
sometimes you can't get out 
no matter how loud you shout 

C Am x4 

but you're holding on tight 
it will be alright 
its okay to let go 
you know 

ENDING: G F C
