surrounding him.

The boy thought he had awakened and was going back to
sleep.
The boy tried to awaken himself from the dream but failed to
do so.

He feels worthless and dehumanized.  He feels like his life is not worth living.  

Explanation:

He no longer has any way to move about as he did before and he is in pain.  He does die.

You could write this from two perspectives:

He is insane and his mind drove him to believe he is a bug.  

He honestly had a physical change and therefore he dies since he feels he cannot do anything anymore and he cannot work to take care of his family.
