Hey guys, So I have a friend he is like a brother to me, He recently just completed his time in the Army at Ft.Campbell he was apart of air assault. He did two tours his first one he came back he was fine nothing changed wouldn't have even known he went over. Did his second tour NOW he isn't himself. When he was back at base after returning I could just get a feeling he wasn't my brother who left. He isn't the sarcastic d***h*** I knew. I figured well he just re-adjusting he will be fine so I didn't question anything. I spoke with my wife's father he just did 25 years active and multiple tours ect... he said give him some time. He recently came home 3 months ago and we'd get up have some beers and just clown around. But not him he just isn't himself. So lately i've been watching him closer and his sister has come to me about him. Apparently he now drinks from the time he wakes up till he blacks out at night. I've seen him kill 2 30 packs and not get hammered so I know he's been doing it for a while. We tried taking him to the range he WILL NOT touch a gun almost like he is scared to. So just today I said screw it and had his sister come meet with me and she has informed me on his last tour he watched his childhood friend lose his life and he was diagnosed with survivors remorse (don't know what that is) and also PTSD. What do I do now??? It seems he won't open up but he is on a course of self destruction.
