don't you think we ought to know by now?

Haiii. Sometimes, I wonder why bad things happen to good people. Karma is one thing, but the fact that circumstances make us go through such terrible an unwanted things in life really makes one wonder why life's the way it is.
It's not fair when somebody close to us falls sick. There is so much pain, so much agony, so much misery, you just don't know what to do, and why it's happening to somebody you love dearly. And times like these, you'd wish there was something you could do to ease the pain, share the burden somehow, just do something!
It is frustrating. It affects you deeply.
What do you do?
Sit back, have faith and hope it'll all turn out right?
Does it help alleviate the pain?
Does it fix what's wrong?
Does it give answers?

It saddens me.
I wish I could do something, anything to make you feel better.
