I am so sorry to hear this, and I hope you are home soon. Doctors don't know everything and I think sometimes they are just as much at the mercy of these big pharmaceutical companies as the rest of us. They come in every week in their suits and carrying a briefcase full of samples that these HMOs force them to hand out. Most drugs aren't even done being tested yet and they have no idea what they do.
A holistic approach would be of more benefit. Especially meditation, yoga, tai-chi or something similar, when it comes to mental well being. And being able to talk to someone close to you is always a plus, oh and animals. My pack are all my PTSD dogs. Nothing staves off an anxiety attack better than a dog pile. =D
