(Please see update at the end of this post.)
You may have heard about virtual reality being used to help people with PTSD. Until now, I hadn't had any exposure to the idea, but then I saw this article talking about the T2 Virtual PTSD Experience. It's an island in Second Life that's set up to allow you to get information on PTSD in a very interactive setting. In order to get there, you need to sign up for a free account on Second Life, download the software, and login. Once you're logged in, you get a short interactive tour to learn how to move around in Second Life, and a chance to set up your avatar.
More detailed instructions are here (t2health.org). There's a video there that describes how the experience is set up, and what to expect when you get there (watching it convinced me to try visiting.)
I think one of the most helpful things about the Experience is that you're anonymous-- you can set up whatever username you want, dress the way you want, and unless you engage in conversation, it's a solo experience. You will probably see other avatars walking around, so you're not technically alone, but you aren't required to interact with anyone. I found it to be a good experience, although there were a few times in the mall that I was startled by images and noise-- but that's how the real world can be.
There is also a conference center, and even a bar in the mall. The Experience may be a good place for vets to meet up without all of the stuff the real world adds on. Hmm.
Anyway, go check it out.

Update: since writing this post, I've had two comments posted regarding Fearless Nation (http://fearless-nation.org/), including one from Colleen M. Crary, the founder of the organization-- definitely go check them out by clicking on the comments link below.
The use of virtual reality to cope with PTSD is still really new to me. My first experience with the concept was a few days ago when I initially wrote this post, and I'd never come across Fearless Nation's website (or presence in Second Life). If anyone has any additional virtual reality and PTSD resources that are publicly available, please let me know and I'll be very happy to pass the word.
