Consider joining a grief support group. They are usually an accumulation of traditions or customs created by families to be shared with family members. When a member of the family is no longer there to share a cherished tradition, the holiday can become a painful reminder instead of a time of joy. The first time you celebrate a holiday after a death, it may become a nightmare. Holiday gifts that once were ripped open immediately may sit for days.
Thanksgiving is hollow.
New Year's Day and birthdays, which celebrate another year of life become reminders of death. You may find the need to develop new traditions. For some, a trip out of town at holiday-time may be beneficial. A birthday can be observed by donating to a charitable organization or doing something that is meaningful to you. Sometimes being with other family members and talking together about the good times experienced in the past can be a source of strength.
