Who's guarding the front door?

It's ok, you're gonna mend yourself soon
you've learned your lesson, yeah you learned it good
It's not too late, you know
It's not too late
Just don't you hold your breath again
Or you know you'll suffocate
You're soft as clay, come on get strong
Where's that steel inside? Oh where has it gone?

No more wooden jail cells
Get your guards up, Get your locks on
Start building your walls up
They've been torn down, yeah they're all gone
Feel what you used to feel
Get colder, get smarter
Cuz if you don't you're not gonna survive, no
Things will only get harder
Don't send me all these signals
When my brain's always right from the start
You're shaking now, You're breaking now
But be strong, be strong, my heart

It's alright, you're gonna figure it all out
you've made mistakes, but now you know what hurt's about
It's not too late, you know
It's not too late
Just don't let down your guard again
Don't you overestimate
You're weak as rain, come on get strong
Where's that fire inside? Where has it gone?
