This page lists positive coping skills for difficult times.
Essentially taking an active role in your healing ('approach coping') is better than taking a passive role or avoiding the problem. Approach/tackle coping means learning about your condition (be it PTSD or other), learning coping skills and seeking social support. Things not to do are going into denial, self blame and partying too hard. Those are called avoidance coping and they keep you from healing more quickly. (Bloks et al., 2004)
Other helpful things that researchers recommend are activities such as moderate exercise, information seeking and relaxation. (Broder, 1996)
