The letdown

I can hear your heartbeat I've tried so hard to forget
I'm being buried under the memory of all of my regrets

I've spent ages losing sleep
While strangers warmed your bed
I know it's over, please be over
There's nothing left to save

Let me let you down
I can't watch you drown with me

Your voice is ringing my ears, but I can't see you talk
You could tell me to go straight to hell
and I'd enjoy the walk

I've spent ages losing sleep
While strangers warmed your bed
I know it's over, please be over
There's nothing left to save

Let me let you down
I can't watch you drown with me

If I could make it simpler
If I could get back to the start
I would keep you even closer
So that I could hear your heart
But your pulse has started fading
I'll try to hold on to the sound
I know it's over, please be over
Because I'll just let you down
