Dear Facepunch: Help thy with my Shakespeare homework

[QUOTE=Macbeth]
My thought, whose murder yet is fantastical,
Shakes so my single state of man that function
Is smothered in surmise, and nothing is
But what is not

[/QUOTE]

Okay so what's the significance of this & what is Macbeth referring to here?
This is the last question on my English booklet due tomorrow and I could really use some help on this.

My appreciation goes to anybody who gives a serious answer.

He murdered a guy in reno and smothered himself in someones breast...

In all seriousness, just look up the words you do not know

To be honest, I am pretty sure I understand all the words there, I just do not understand how they fit together.

Why don't you google the quote and find out what it means?
