It seems as though Jon did an excellent job at policing, even though he dealt with a lot of trauma. He struggled and attempted to work through it, but knew when to take some time off due to his mental health. Even with PTSD, Jon uses his time, energy and experience to help others with mental health issues by creating programs and fundraising for the cause. He could have given up but didn't....he now easily sympathizes with others who are experiencing mental health issues and works to erase the stigma associated with such!
