When I work with emetophobics in therapy one of the things we do near the beginning is to decide on a peaceful image/scene that they can imagine. For many people its a beach. For some, a cabin in the mountains. Believe it or not the brain doesn't know the difference between seeing a scene with your eyes and remembering (or imagining) the scene itself. The great thing about this is that you can use this phenomenon to help you with your anxiety. It's not an "instant cure" or "quick fix" however. It takes time, so you need to stay with it.
If you could imagine the most peaceful place in the universe (real, remembered or imagined) where would it be? Would you be alone or with someone else?
