I have researched ad nauseum, solutions for those suffering from PTSD. Whether the diagnosis is from combat stress, domestic violence, witnessing a crime, or a tragic event like an earthquake, there are ways to relieve the symptoms in conjunction with medication.
One that I strongly believe in is eye movement desensitization and reprocessing or EMDR. I would like to recommend the book "EMDR" by Francine Shapiro, PH.D. and Margot Silk Forrest. There is a center here in Colorado Springs, CO that is known nationwide for its practice of EMDR with combat veterans. Nobody likes to feel sick and unable to do basic tasks around the house. That is no way to live.
Another activity that relieves my anxiety are hikes in open areas. Hyper-vigilance, or the need to know who and what is around you, can be exhausting and induce a feeling of nausea. I like to take my dogs on walks to areas that I know are safe and open. The least amount of trees the better. I have also found that short stints of gardening around my house on a summer day helped me relax. I had to limit that time to one or two hours at the most. Otherwise, anxiety would kick in and I would have to lay down and take a nap.
Owning dogs has played a role in my over-all health. Physically and mentally I have benefited from playing, hiking, and laughing with my animals. The dogs have forced me to get outdoors when I clearly preferred to stay in. Getting outdoors is great for reducing anxiety as long as you are not in a crowded group setting. I steer clear of shopping malls during busy hours, fairs, amusement parks, and Walmart on the weekends or nights. Know your limits.
Eating, sleeping, and exercise are a must. Your body needs balanced meals for good neurological health. The brain needs REM sleep in order to deal with subconscious thoughts. If a person is drinking alcohol, not only does that mess with medications, it also inhibits REM sleep. If your mind cannot deal with issues that are bothering you deep down, then you are literally going crazy. Exercise and sex are the two things that make an anxious and depressed mind feel better because of the serotonin that is released. The more you can do of these two activities, the better off you'll be.
Remember that therapy and medication only go so far. After that it is up to you to do your part. You must fight for your life anyway you know how. Research and act upon what you find. Waiting around for someone to give you your life back could be a long wait. And if you do all that you can and still find that you aren't getting better, then it might just be a need to adapt. Isn't that what they say in the service: "Adapt and overcome"?
