Verse 1:
                   Ab
Looking at the pictures I keep on my shelf
                     Fm
'Cause it's been so long since I've looked like myself
                Eb
Burn another candle down
                Eb
Burn another candle down
                Ab
Running low on patience, running low on fumes
                    Fm
I'm never gonna make it halfway to the moon
                     Eb
But it's too late to turn around
                     Eb
But it's too late to turn around

I'm running out of oxygen

Same again now

Ab
Oh my god, I can't remember

Who I was just last December

What have I done, how did I get here?

Oh my god, look in the mirror

I was young, nothing to fear once

What have I done, how did I get here?
Eb
What have I done?
 
Verse 2:
             Ab
Maybe I was foolish, I guess I was naive
                   Fm
I didn't know what I had, and I thought I had to leave
                    Eb
I wish that I was homeward bound
                     Eb
I wish that I was homeward bound
                   Ab
I'm searching for a signal, holding out my phone
                Fm
Have I gone too far, am I on my own?
                Eb
No one here to hold me now
                 Eb
No one here to hold me now

I'm lost just like Will Robinson
 Eb
Or rocket man in space

What have I done?
