John Mayer - Something's Missing lyrics

I'm not alone i wish I was
'Cause then I'd know I was down because
I couldn't find a friend around
To love me like they do right now
They do right now

I'm dizzy from the shopping mall
I searched for joy, but I bought it all
It doesn't help the hunger pains
And a thirst I'd have to
Drown first to ever satiate

Something's missing
And I don't know how to fix it
Something's missing
And I don't know what it is at all

When autumn comes it doesn't ask
It just walks in where it left you last
And you never know when it starts
Until there's fog inside the glass
Around your summer heart

Something's missing
And I don't know how to fix it
Something's missing
And I don't know what it is
No I don't know what it is at all

I can't be sure that this state of mind
Is not of my own design i wish there was an
Over-the-counter test for loneliness
For loneliness like this

Something's missing
And I don't know how to fix it
Something's missing
And I don't know what it is
No I don't know what it is
Something's different
And I don't know what it is
No I don't know what it is

Friends (check) money (check)
A well slept (check) opposite sex (check)
Guitar (check) microphone (check)
Messages waiting on me when I come home
(check)

How come everything I think I need
Always comes with batteries?
What do you think it means?
How come everything I think I need
Always comes with batteries?
