This is The Flatliner's cover of Dead To Me's 'Arrhythmic Palpitations' 
From what I can gather he's singing the lyrics a little differently. 

 C/B:    F:

Intro: C, C/B, Am, C/B, (x2)

Verse 1:
C                     C/B                   Am     C/B
In the middle of the night I can do it just right 
   C             C/B              Am     C/B
It seemed like a good idea at the time 


Chorus:
C                F
And the morning I will  
      Am
Say goodbye 
      F                  C         
With all the things that I've 
C/B               Am
I've been running from
G                     F     F (Argpeggio)  
Remember how scary it was? 
G
Funny how everything does 


Palm-Muted Intro: C, C/B, Am, C/B, (x2)


Verse 2:
C                 C/B                   Am    C/B
So I drive right in, but the current is swift 
C              C/B                Am      C/B
My arms won't swim and my legs won't kick 


Chorus 2:
C              F            Am
I start sinking (humiliation)
             F                        C
Start sinking arrhythmic palpitations again 
          C/B              Am
Then the walls come tumbling in 
G                      F     F (Argpeggio) 
Remember how scary it was?

All the reasons why

You're here
G           Am         
Become the reasons why
F       C
Don't say
