Four. The advice that is meant kindly

Have more sabr. Be grateful. Do more dhikr. Think of people worse off than you.

Every one of those is said with love and every one of them lands as an accusation, because you are already trying and it is already not working. What the person hears is that they are failing at something simple.

Al-Ghazali treats sabr as a capacity that is exercised and trained, not as sitting still and waiting. That is worth knowing, because have sabr is the single most common thing depressed Muslims are told, and it is almost always understood as do nothing and endure.
