Cover art for Breathe In lyrics by Hit the Lights

It sounds more like "Nerves numb" than "Once numb" at the beginning of the second verse...

This is what I heard.

"Nerves numb When conscience comes crashing I'll keep strong Take time to find yourself But 'til then, I'll be waiting on you to come around And you will"
