Father's campaign: More time off for grieving parents

If you know people who may be experiencing survivor's guilt, check in with them frequently, Brymer said. How much is this consuming their lives? Are they able to attend to their basic needs? Are they so overwhelmed by their feelings that they're stuck? One coping strategy is to do something meaningful for someone else, Brymer said. Organizations that help people who have survived violence or natural disasters, or advocacy groups, may be good options for people who are trying to move on from a tragedy such as the Colorado shooting. It can also be important for a survivor to honor those who died, Brymer said. "If someone has died, is there something that you can do that's meaningful and representative of that person?" she asked. "Is there something you can do so you're unstuck, so you can do something powerful and meaningful to someone else?" Some people may also change expectations for their future as a result of surviving a traumatic incident. Young, for example, told NBC's "Today" that she wasn't sure whether she should remain in Colorado. It's important to make sure that life changes aren't negative, Brymer said.
