Bm                   A/C#
We're standing on a ledge
                   D
We're facing an abyss
                 Em
Frozen solid, petrified
                     Bm
The stakes are fathomless
                         A/C#
There's tension and it's toxic
                 D
I dare not even speak
                                 Em
Our hopes and dreams are on the line
                      Bm
The future's looking bleak
Gmaj7       Bm       A/C#  
Dispatching doves in earnest
A/D        A         D
In hope to find dry land
D/A           Em
Waiting for a sign
Em/G         Em/F#           Bm
That there are better times ahead
Gmaj7   Bm       A/C#
Unstable and reactive
A/D        A         D
There's nothing left to say
D/A           Em
But to avoid ignition
Em/G Em/F#         D
To survive another day
D           G
I'm holding on
Em            A              A7  A6
But for how long until we're falling?
D           G
I'm holding on
Em            A              G   G/F#
But for how long until there's nothing?
Bm               G   G/F#
Before there's nothing?

Bm A/C# D Em Bm A/C# D Em

Bm                 A/C#                 
This heart is suffocating
                    D    
I barely feel its beat
                  Em
These nerves are tied in knots
                              Bm
And I'm struggling hard to breathe
                   A/C#
You say that I'm depressed
                              D
And that's where our problems lie
                            Em
Yet you're the one who's screaming
                        Bm
Crying, hating all the time
Gmaj7   Bm       A/C#
Constantly erratic
A/D        A         D
You're overwhelming me
D/A           Em
One wrong word or action
Em/G         Em/F#           Bm
And we are history
Gmaj7   Bm       A/C#
So show me a solution
A/D        A         D
If there's one at all
D/A           Em
I hold on cause I love you
Em/G         Em/F#           D
I'll still love you if we fall

D           G
I'm holding on
Em            A              G  G/F#
But for how long until we're falling?
D           G
I'm holding on
Em            A              G   G/F#
But for how long until there's nothing?
D           G
I'm holding on
Em         A
Until it's gone
D            G    Em  A             G  G/F#    
But for how long       until we're falling?

D           G
I'm holding on
Em            A             G  G/F#
But for how long until we're falling?

D           G
I'm holding on
Em            A               G  G/F#
But for how long until we're falling?
