I thought this was a good way to put this, so here it is.

PTSD is an entirely normal reaction to an abnormal amount of stress. Having PTSD does not mean you're mentally ill, nor does it mean that you are weak or somehow deficient. Instead, think of it this way; no matter how strong your leg bones, if enough force is applied, they will break. Given the proper care, they will heal; and so can you.

In some cases a leg may be so damaged that it may never return to its original state. Your losses may be similarly enormous, however; with support you can find ways of coping with your permanent loss and discover new talents to develop and new reasons for living.
