When depression hits men, they are sometimes the last to know. Others tend to see it in their short temper, erratic or over-controlled decisions, work absences, defensive of themselves, while hypercritical of others. Anger management problems often appear as a mask for depression, as many men have learned early in life that other forms of emotional expression are signs of weakness.
