What insights can you offer to family and friends of a person suffering with PTSD when they're contributing to the person failing recovery?

Find a trusted counselor and arrange an intervention for the family. Maybe a chaplain or someone else trained in trauma work.

I Haven't had that problem with family support, it's also only been recently things that didn't bother Me at the time I served in Vietnam in 1968-69 now Come up in nights as strange dreams. I seem to feel that there are plenty of people that went through more than I did. Also after 40 years of Police work both Military and civilian the number of call where Physiatrist were the problem themselves on far too many family disturbance calls. A lot of them had their own mental health problems in My opinion and i didn't trust them to solve My own. One Physiatrist friend of mine told Me about 85% of His own fellow shrinks entered the field to find out what was wrong with themselves. On some of those calls it was the so called Mental Health professionals were the problem and NOT the family member they called about. In some of those cases it was the Doctor I either arrested or determined they were the problem. it's not family support but lack of trust in these Physiatrist to go there with My problems. I seem to do better with My own fellow Veteran's than many of those Doctors. I have had college courses in Psychology but I'm NOT a Doctor or expert in that field but i know a nut when I see one and many of these Doctors qualify as just that !

The science does not often get it right for military members. Day one when we enter military service it is all about the team and mission, and this is very different from civilian life. We then try to fix the problems by making it all about the person. We need to fix it the same way we broke it, as a team member and focus on the hurt person being a member of a team like they were on AD. We need to show them their team needs them just as much as they did on day one of active duty.
