I can't think of any reason for seniors to worry and become depressed except for their retirement savings may not outlast their lifespan with the current rate of double digit inflation yearly. 
Most of them have planned a retirement sum which should last them with inflation rate about 10 years ago.  Unfortunately, many were caught off guard with the current astronomical rate of inflation which some were caused by the PAP with GST, transport, utility, and rental hikes leading to across the board increment in cost of living. This is the area causing sleepless nights, stress and depression to retirees.
