In the third stanza the speaker focuses on himself and the effect this situation is having on him.
The repetition of
I will not feel is testament to the speaker’s determination not to allow his emotions to overpower him.
We can imagine this shows the speaker’s fear of being overwhelmed. He worries he will break down, unable to cope with the painful reality of the situation.

The use of enjambment especially emphasises the word “feel” and clearly conveys how desperately the speaker would like to remain numb.
