Since I've been alone

I cant think of a time when you
Eb

My mother said

To talk things through
Cm
Don't let heavy hearts pile up on you
Eb
But how can I
                        Cm
When I'm too scared to speak
A#          Cm
I cried all night
G#               Gm                   Fm(2)
But I put in too much to turn away now

Eb
I've been waiting for you to say
Cm
That I'm better off

Without you

I cant count the days
   Cm      Gm

Everyone looks the same
