Post traumatic stress disorder (PTSD) usually lasts for a long time, and in some may last all their life (Olszewski and Varrasse, 2005). In addition, one-third of those with PTSD fail to recover, and PTSD often co-occurs with other psychiatric disorders (Kessler et al., 1995).
The good news is that you don't have to wait around for PTSD to just go away. You can actively get help for PTSD, and you can reduce your symptoms by learning more on the development of PTSD, and how to break the negative, vicious cycle of PTSD.
