I must admit though, many people with PTSD can actually work again, its just they can't work in certain environments. Putting someone with PTSD to deal with customers is not a bright idea, for obvious reasons. People with PTSD generally can work in low stress environments, work for themselves or non-profit organizations, and many other low stress workplaces.

Yes, a person may need to curl up for a year or two and work themselves out first, but most should be capable of returning to some form of work again. It is recently studied that to help cope with mental illness, some sort of return to work program is one of the best options to get a person moving again, becoming functional within society, grasping social facets of life again, basically everything that PTSD works against us.
