Read what the Trench verses describe

Hearts reaching the throats. Eyes swerving. The believers shaken with a severe shaking.

That is not a metaphor for mild discomfort. That is an acute physical fear response, described in the Qur'an, happening to the Companions, in the presence of the Prophet, peace be upon him.

If a panic response were evidence of a faith problem, this is the passage where you would expect to be told so. You are not told so. The passage describes the state and moves on.
