Is the questioning and contemplation that took place within her doubt or whispering (waswasah), and is she an infidel, or does she remain a believer?

What the questioner is experiencing does not lead him to disbelief, and his doubt about uttering a statement is not to be taken into consideration. This is because apostasy from the religion only occurs when one is certain of the occurrence of something that contradicts monotheism. What the questioner mentioned is nothing more than self-talk, satanic whispers, and fleeting thoughts that the heart does not settle upon. This does not necessitate disbelief, nor is one held accountable for it religiously, for Allah has forgiven this nation for what they talk to themselves about, as long as they do not act upon it or speak it.

And if self-talk relates to creed and faith, and the self rejects and dislikes it, then this is a clear sign of faith. The Muslim is rewarded for striving against these whispers.

As for what the questioner feels when reading verses about the punishment of disbelievers, he should address it by frequently contemplating the texts of encouragement (targhīb) and deterrence (tarhīb), and always remain between fear and hope. He should strengthen the side of hope when Satan tries to make him despair of mercy, and strengthen fear when he tries to make him feel secure from Allah's wrath.

Whispering (waswasah): is something that assails the heart without a person's choice. If the servant dislikes it, his dislike indicates clear faith. As for doubt (shakk): it is the opposite of certainty, and it is hesitation between two things.
