Envy of those more fortunate bad for the soul

My sibling works in insurance. To be more precise my sibling works in a department within a monstrous insurance company that specialises in life insurance. Sometimes we talk to each other about our depression.
You see, there is a particular day when life insurance claims spike. It coincides with the first credit card bills appearing on the doormat after the relative happiness of Christmas. It also ties in with a run of limited daylight that stretches from the shortest day on December 21st through to the first week of January.
