Your character might also experience mood swings, sleep issues, anger flashes, impatience, crying, lethargy, hopelessness, disinterest in things they love, weight loss, inability to remember or focus on things, etc., when in the midst of heavy grief. They may have days and weeks where they are fine and then suddenly dip into a depression of sorts where they upset easily.
It's a pervasive sadness you can't run from.
