Allow littles or other inside parts to discuss their fears about the date. This is best done in therapy, although there may be times, such as the Health club incident mentioned above, when this isn't possible. Letting inside people draw their concerns, and slowly share their memories of the date, can go a long way to deactivating the fear around the date. Knowing this can happen, the survivor can try to take extra good care of themselves. Eat nutritiously and get rest.
Emotional stress is very tiring, and can tax a person's reserves.
Try to build these reserves up during anniversary times. Try to lower your stress level. Anniversary times are NOT the time to overload or do too much. This might be the time to plan for vacation time from work, taking a sick day, or otherwise bringing down the outside stressors. I have a day with nothing planned at all.
