You can't save everyone, right?

You can't save everyone, right?
but I feel helpless seeing her even with her last dime thinking of someone else need.
She would live in starvation for their bellies to be full,
for I am just a child wanting to help but can't even help my own mother.

You can't save everyone, right? 
but when she falls I see her eyes filled with tears yet showing a smile.
She would live in discomfort so they sleep soundly in their warm beds while even her soul freezes
Why is life so hard for her

When I hear a sad song I think of you, grandma picking up everyone while you are struggling yourself.
Wait a couple of years more grandma, don't leave yet before I can give you the life you deserve. I promise when I'm a bit older your soul will fill alive again.
You can't save everyone, right? I will save you.
