These walls in Book 1

What do you expect when the walls keep tightening?
What do you expect when the walls start talking? 
What do you expect when no one else is listening? 
I can't keep it all together anymore 
And I'm not sure if I tried I'd want to 
So let it go, let me go 
Try to see me tomorrow 
But if I'm not here 
Just know that I tried my best,
Just know that I told those that I cared for that they mattered
Just know that life is better spent looking forward than back
Just know that it's always better tomorrow
