It's called life

It's something to big to comprehend
Won't fully understand until the end
So many difficult and sad issues
Tears so big, you'll need more than a few tissues
All the lucks run out, where do you turn?
This world is cold but it'll still burn
Everyday is a new struggle
After ever corner you'll find more trouble
It's all so confusing
It'll make you think twice
You ask what I'm talking about..
I'll say its a thing called Life
