Other than deaths of somebody, what is the most hurtful thing you ever know?(If you are a lover of anyone around you.)

Of course its parent divorce, OMG. Why? ):
I hate to see my friends getting hurt and cut themselves because just to make their parents not to get a divorce, and... its hurtful, I wish I could help out my friend... I wanna scold their parents...

I wanna help... But its impossible, I don't have the right to scold them... I'm just a somebody they see as a stranger, but for my friend, I'm a friend to her.

I think I'm going to buy something for her later after my tuition. Maybe something that is, useful and would help her, but where could I find this holy holy holy usefulness item?

How I wish this world doesn't have any sadness.
