I like the idea of seeing a gp, maybe he will be opened to it and I agree that if you think he is in immediate danger please seek help. Maybe you can try to talk to him about this issue and your concerns, there are a few things that he could probably be diagnosed with that would help explain to him why he is struggling so much. I am by no means trying to diagnose him but my main concern would be the depression and possible ptsd, these things should be treated by a professional.
