There are just somethings that you yourself do that you find it unforgiveable

I have come to this conclusion today, you can forgive anyone but yourself.
Just like what I have remembered seeing on my teacher's Facebook status, her friend commented that the person torturing you is actually you yourself.
This might sound weird but come to think about it, isn't it true?
We just can't stop harping on the problem which make us feel sad and despondent,
But there's just no way we can let go...

talk to my hand.
