Please don't assume that just because you can't see a disability, the person doesn't have one. I care for my sister, who was awarded her disability benefits on the first try without the benefit of a lawyer, but you would not know about her disabilities just by looking at her. We had the support of 7 doctors who backed her application. PTSD is only one of the issues, physical, emotional and mental, that she deals with each and every day. She could easily get a service dog, but our Orick, himself a survivor of abuse and neglect, has assigned himself that position and is invaluable to me in caring for her. Right now we are awaiting a test that will determine whether she will be going into the second round of her fight with cancer.
