Personally, I think the song is about his vision of his girlfriend as an angel to him, he thinks very highly of her. Then one day, she is hit with a sickness (a storm) and she falls (gets sick). He doesn't have the will in him to tell her that she is really sick, and probably won't make it. He doesn't want to cry by her bed and let her see him, because then she would know the severity of it.
