Holidays can produce moments of acute depression for the person alone. Even for people who live alone happily, holidays can be difficult. This is changing. Create new traditions. I've looked forward to Thanksgiving dinner with my church family.
Someone makes the turkey and everyone else brings the trimmings and desserts.
Helping out at a homeless shelter on Thanksgiving or Christmas can start a regular volunteer activity. These people need help all year round. You can also be assured that the holiday season eventually ends and you can make it through. It's just another day of the week. Many people, especially those in the medical, retail and hospitality fields don't know what a traditional weekend is.
