Verse 1
        Abm
Did you ever picture life like this
     E
No shooting star to grant your wish
        C#m
Are you everything you hoped you'd be
    Eb
Or caught somewhere in between
      Abm
You dropped your nickel down a wishing well
       E
And prayed for luck to cast its spell
     C#m
To bring you closer to your dreams
      Eb
That always seem just out of reach

Pre-chorus
      E
You pray to God the moment when
     C#m                         Eb
You feel the current pull you in

Chorus
                  Abm
Try to keep your head above water
      E
Has never been harder
       C#m
Even when it feels hopeless
        Eb
You're gonna get through this
  Abm                    E
Head above water, gotta fight from going under
       C#m                     F#
Even when it feels useless to wish
                              Eb..pause
You're gonna get through this

Abm

Verse 2(like 1st)

Have you ever felt like giving in
Tried for hours but just can't win
Tell yourself you're not good enough
The struggle alone is just too much
No one's there to hear you scream
You gasp for air but cannot breathe
Did you ever think you'd see the day
When you'd watch your life get washed away

Pre-chorus

Chorus

Bridge

Abm
  Did it ever hurt so bad
           E
That the thought of feeling lost would never end
     C#m              F#
Well you will think again

Chorus
Abm                E
Head above water, never been harder
C#m                                   Eb
Tryin' to keep your head above water has never been harder
                          F# Abm E C#m
You're gonna get through this
                          F# Abm E C#m
You're gonna get through this

End with F#
