it happens at alarming rates! living with a combat vet I know he tried many times. I know others that tried numerous times. one of the biggest issues that I saw was they guys didn't feel like anyone understood what they were going thru and therefor did not talk about things they went thru in combat. the other thing was that they were not treated properly in alot of cases. medical/psychological. there is a great need to find just the right combination of medications that will work and a great need for the veterans to communicate thing that happened.
the more you talk about it sometimes the better off you are.
