Hello, I'd like to help you with your question.
Any phobia, no matter what it is, is rooted in anxiety
. Fear of vomiting is the same, a fear of how you feel when confronted with vomiting. Anxiety is created when your thoughts are cause your mind to think your in danger, such as when you see someone get sick. That began when your father would come home drunk and dry heave. The sights and sounds of seeing your father created a strong fear reaction for you. Because of that, when you think of someone vomiting, your body reacts by releasing adrenaline into your system. Adrenaline cause you to feel the body symptoms that are common with anxiety. It is much like after you have had a bad scare except with anxiety, there is no focus. The only thing you have to focus on is how you feel. And because your thoughts are probably always on alert, so is your body. This may be why you always feel anxious and scared.
The good news is that anxiety is easy to treat with therapy. In therapy, you learn to pay attention to what you are thinking to make yourself anxious. You can also deal with the root of your fear, which is how you felt about your father. The therapist then can help you change your thoughts and therefore how your body reacts to your thoughts. And by dealing with the root of your fear, you can take the power out of the anxiety. You also can learn about how to let yourself float through your anxiety thereby gaining more control over how you feel. When anxiety comes on, you allow it to flow over you without tensing or panicking in response. This makes the anxiety reduce or go away faster. To find a therapist, talk to your doctor about a referral. Or you can search on line at http://therapists.psychologytoday.com/rms/.
Medications are helpful to ease the symptoms but they vary in their effectiveness. Each person has their own body chemistry and what works for one may not work for another. Also, once you take medication for a while, your body becomes accustomed to it and you either need an increase in dosage or you need to try a new medication. But medications can help to reduce your symptoms quickly so you can work on overcoming your fears.
You can also help yourself at home. There are numerous resources to help you learn more about anxiety. Here are some to get you started:
