It's very unhelpful, and it can set them back a long time. I've had some veterans tell me that they went to see a psychiatrist for a year, and they were being completely honest and completely open, but it was only through the peer support that they really started to understand, being in a group setting with other veterans, that they were talking about things that weren't the root of the issues. They thought they were giving the psychiatrist the right answers, what the psychiatrist was looking for, but they weren't dealing with the root cause of the PTSD, which actually happened many years before service.
It's a learning process on how to use the services out there effectively, I think.
