1) If you can afford private therapy from a CBT therapist who specializes in anxiety disorders, that is the best way to go. My own Skype practice is full right now with a wait-list of close to a year, but I'm not the only one who can treat emetophobia successfully. There are dozens of therapists world-wide who can and are treating it. The key is to find one who you really like. Someone who is warm and compassionate, and who you really "click" with. Private therapy can cost $100-$150/hour and you are looking at at least 6 months if not a year of weekly visits. Pricey, but then again would you rather have a car than your life back? (One way of looking at it - and I understand that many people need their cars!) Part or all of your cost may be covered by insurance in the USA and extended health plans in Canada or the UK.
2) If you can't afford private therapy - and many people can't - there is a lot you can do to help yourself. First of all the Emetophobia Recovery System, while I don't endorse it as a treatment, is still a good solid program as far as managing your anxiety in general is concerned. And for around $100 it's cheaper than one visit with a therapist. Secondly, you can check out the "self-help" section on the resource page of this website. (It will take you to my other site which is all about treatment resources)
3) Take the relaxation exercises very very seriously. Learn to breathe properly and relax your body by practicing the skill at least 90 times. That's 45 HOURS of practice. You can't possibly just "tell" your body to relax and to breathe more slowly. It's a skill like learning to play the piano (although it takes a lot less time!)
I wish you all the very best in 2013 and hope t
