Circus song

4 o'clock panic sets in
Thoughts don't stop of us back then
I woke up forgetting you
Day flew by' til afternoon

And as the day's growin late
Memories i thought had faded
Rush right back into my head
And they don't stop
No they don't stop

I step outside for some air
Chide myself for being here
Stuck within our history
Can't hold on but won't break free

You're some new part of my brain
Stranded in my dna
I thought was over you
But i'm not i'm really not

How long, how long
Until love's gone?
