Letting go

Is it okay to give up on the day
to just let things lie where they may
Is it okay to rest my weary head
to say "screw it all" an go back to bed
Is it okay to fail to try
to lay in bed and let the day go by
Is it okay to feel this bad
to not be sure why I'm always sad
Is it okay, and really, am I
to constantly be asking, why? Why? Why?
