How does Lady Macbeth show strong emotions throughout the play in Macbeth?

Ladyis definitely very
interested in having her husband be king.  Once he begins his homicidal spree, she has strong
feelings of guilt.

Ladybecomes very excited when she hears
that Macbeth has been prophesized to be king.  She is ambitious, and wants him to have the
biggest office.

Make thick my blood,

Stop up the access and passage to remorse,(45)

That no compunctious
visitings of nature

Shake my fell purpose nor keep peace between

The effect and it! (Act 1, Scene 5, p. 20)

is
interested in Macbeth coming into power at all costs.  When he falters, she pushes him.  She
calls him a coward and tells him she has a plan, he just needs to follow it.

But screw your courage to the sticking-place,

And
we'll not fail. (Act 1, Scene 5, p. 24)

Once Macbeth
kills , she is still calling the shots.  She scolds him for not putting the daggers by the
victims.  She insists that he play it up, and sound sincere.  They both do an excellent job
acting surprised.

When Macbeth does not stop at killing Duncan, Lady Macbeth
is annoyed.  She tries to stop the ball she started rolling, but Macbeth is no longer under her
influence.  She becomes more and more guilt-ridden, until she has a mental break.

What need we fear who knows it,

when none can
call our power to account? Yet who would

have thought the old man to have had
so much blood in(35)

him? (Act 5, Scene 1)

She eventually succumbs to grief and kills herself.
