I made this tab from a bunch of Youtube Videos and with the hope that someone else 
will make better tabs, so feel free to critique.
Watching the videos will help too btw.

Intro
C-G-Am-G-F-G

Verse 1
C         G             Am
Toss and turning around
G            F
Hearing life's crazy sounds
    G
Outside my window
C         G            Am
I'm gonna stay here in bed
        G      F
Covers over my head
     G
I feel so tired

Prechorus 1
Em 
The world can wait for me
Am
'Cause the past few nights, I couldn't sleep
F
'Cause I've been thinking about you lately
G
Driving myself so crazy

Chorus
C           Em
Please come back
Am
I want you here
F
Right by my side
C           Em
Oh, please come back
    Am            F              C
Oh, girl, I need something to believe
Em              Am              F
Something to believe

Verse 2
C    G    Am
If I only knew
       G     F
How to reach you
    G
I'd grab your hand and...
C        G           Am
take you where you belong
       G       F
Here inside my arms
               G
Hold you close, that's what I'd do

Prechorus 2
Em
I'll just wait for you
         Am
And you could maybe make my dreams come true
              F
Oh, I've been thinking about you lately
    G
The thought of you makes me crazy
