This a really simple song. I'm pretty sure this is correct.

The chords you need to know are:

D ~ A ~ G ~ Bm

Capo:1, but you dont really need one if you dont have thaats just how I play it.

Intro:
D ~ A ~ D

Verse 1:
D             A       D
I've tried playing it cool
D             A       G
But when I'm looking a you
G      A       Bm/D
I cant ever be brave 
     G         A  D
Cause you make my heart break

D       A          D
Shot me out of the sky 
D       A     G
Your my kryptonite 
G        A         Bm/D
You keep making me weak
G            A        D
Yeah, frozen and cant speak

G                      D
Some things gotta get now
         Bm                           A

Verse 2:
D        A           D
Now I'm climbing the walls 
    D        A         G 
But you dont notice at all 
     G         A         Bm

G            A   D
all day and all night

Pre-chorus:
D                     D
Some things gotta get loud

Cause I'm dying just to know your name
      G                     D

I don't, I don't, don't know what it is
    G            A   D              
But I need that one thing

    D            G        A         D
