Sure. The one person I can think of, maintaining confidentiality, was a 21-year-old reservist from my regiment who went overseas to Afghanistan, was injured, came home, and had a knee injury I believe.
He was able to have his contract extended. He was going to be paid full time while he was undergoing treatment, but he was required to report to the unit to do paperwork and things like that throughout the week. It was quite a commute for him to get there.
Going through the process within DND he felt fed up and stressed out by the program. He said that he didn't want to deal with it, and left. That was the last time any of us saw him.
We hear reports that he's okay and everything, but he has just gone off on his own. He has not applied for Veterans Affairs benefits that we know of. He has not accessed any services. That's the sort of stoic military culture that exists.
That is the most common type of veteran out there right now: somebody who had just gone on and done it themselves. I would predict we would see those people coming back, down the road, if they are not getting support and not being successful.
