It is called PTSD! Post Traumatic Stress Disorder. It isn't a matter of enjoying their "job". They are defending their country. They tell stories to have some sort of camaraderie with others who know what they have been through. They may laugh, cry, get depressed, and have many other emotions that none of us can understand unless we've been there. I don't think this is a matter of "poor me", or wanting sympathy. This is a real disorder, that a lot of military men and women have to deal with when they see the unimaginable things that this war has ingrained into their minds.

Your friend may have what is sometimes referred to as "shell shock". It doesn't matter how long ago he was in Iraq, or Afganistan. It could be 20 or 30 years from now, and it could still trigger memories.

Ask if your friend is willing to go talk to a professional therapist, that specializes in PTSD. There are Dr.'s that are specifically trained to treat people like your friend, and help him with everyday issues that will affect normal everyday life.

Good luck to your friend, and respect him for defending your country.

Thanks everyone for all the information :) . (Special thanks to starby and Bigbopper)Good news, two of my friends has sought help and they are doing better, not totally well, just taking one day at a time. They told me something about having a break through and being able to talk to the right person about what's on their mind. They also spoke of being honest with themselves. Once again thanks; oh and one other thing I had no idea that this whole ordeal had depressed me a great deal. Although I have done nothing to help them and I had seemed selfish and insensitive; I was worried and did care but didn't quite understand the PTSD stuff until you all explained it to me. I too feel like a weight has been lifted of my shoulders. Thanks everyone.:D

I'm so glad that the advice helped you and your friends! :) I don't think you were being selfish or insensitive, you just didn't understand what your friends were going through, so when you don't understand, it is hard to give any help. I think it's great that you cared enough to ask your question to begin with!

It's nice to know that we helped out a little bit. Best of luck to you, and we're happy to help if we can, anytime!
