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 malls
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
[ Lyrics from: http://www.lyricsmode.com/lyrics/j/john_mayer/somethings_missing.html ]
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

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 for 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
What do you think it means
