When is Enough, Enough?

Please explain to me why you think this is a joke.
I just don't understand.
You keep pushing me far beyond my limits.
Do you do this because you can?

Do you think stop means continue?
An explanation would be nice.
I want to know the method behind your reasoning.
Maybe so I can have just a bit of insight.

I mean, I've asked you to stop plenty of times,
But you just kept on going at it.
What? Do you find it funny
To watch me fall apart with every hit?

You may not know this,
But your attacks are leaving me weak.
Not physically, but mentally.
My mind is only left with a silent shriek.

I am trying to hold myself together.
Psychically it seems I've got it right.
If you look within me,
You'll find there is no hope of light.

As I am quickly approching my breaking point,
I want you to realize how close I am to my last breath.
Answer to yourself, "When will enough really be enough?"
Will it be when I am far past death?
