If one thing stays with you

Let it be this.

The loudness of the feeling is not evidence about the size of the danger. Worry is a behaviour and not a personality, which means it is something you do rather than something you are. And none of it is a verdict on your faith, because the Qur'an describes the Companions in open fear and does not scold them for it.

The ease is not somewhere else, waiting for you to earn it. The Qur'an says it comes with the hardship.
