I don't know how else to put this

It's taking me so long to do this
I'm falling asleep and I can't see straight
My muscles feel like a melee
My body's curled in a U-shape
I put on my best
But I'm still afraid
Propped up by lies and promises
Saving my place as life forgets
Maybe it's time I saw the world
I'm only here for a while
And patience is not my style
And I'm so tired that I got to go...

it gets harder each second...
