First off, you need a good support system in your life. Share your fears with at least one person in your life, this will go a long way toward easing your burden and will lessen the intensity of your fears.
Very importantly, you should learn as much as you can about training your brain. The brain is a wonderfully adaptable mechanism which can do the most amazing things if given the right tools.
I recommend learning what's called The One Move Technique, a method which trains you to shift brain activity from the emotional midbrain to the logical forebrain area. It alone may be all you need to overcome your
fear of vomiting.
Also, change your diet. The most important things you can do is eat your fruits and your vegetables and get as much lean protein as possible. These foods create the neurotransmitters you need to calm your mood and feel like your old self again.
Meditation and relaxation techniques work wonders, but you have to get in the good habit of perfoming them on a regular basis for them to take a effect. As little as 10-20 minutes a day is enough if you do it daily.
Ever hear of using yang to nourish yin? What this means is exercise vigorously and you will calm your nerves. Basically you wear yourself out and you will not have the energy to feel panicky or nervous. It works, and for some people cannot and should not live without it.
As you've read there are so many things that you can do to treat yourself. Most of the things have to do with lifestyle, and they may sound boring or even trite but they really work.
Remember to check out The One Move Technique, no anxiety regimen is complete without it!
