Anxiety is not Avodas Hashem. Hashem wants us to be happy and calm. Anxiety is a mental condition.
לא ניתנה תורה למלאכי השרת - The Torah wasn't given to angels but to human beings. All we can do is our best.
We clean our homes as best we can, are mevatel and sell our chometz ... and we relax. So we can drop the nerves. Yiras Shomayim is great but not when done wrong. People often conflate their own mental issues with religious piety.
