You're the first thing I think of when I wake up in the morning
And the last thing I think of when I fall asleep
You're my motivation, my inspiration
You're my everything
So, darlin' don't let me down
You gotta hold on, to what we've got
It's more than just a game, yeah
And you know you can make it, yeah
Chorus: Hold on, don't give up
Until the sun don't rise
'Cause baby I'm not giving up on us
And even when I'm not with you
I'll still be holding on, yeah
You might get caught up in the moment
And you might feel like giving up
But you gotta remember, we're not alone
Through every storm, we'll be making it through

But I know I gotta try it
Take a step back, take a deep breath now
And let it go, let it go
Chorus: Believe in yourself again
Even when it all gets too much to take
You'll never have to walk alone
Just believe, just believe
So let go of what you think you should be, yeah
And just follow the feeling that's leading you now
You're not alone, it's alright, yeah
You'll find your way, you'll make it out alive, yeah
