There are a couple things that I think you need to take into consideration or look into:

1. Openness and communication about your fear. It doesn't sound like people know about your fear. There is nothing wrong with it, and it is not something you need to be embarassed about. When other people know about it, it will help your anxiety because others will be able to help you, rather than it being you vs the world

2. Anxiety never helps a situation. What percent of your anxiety actually is over something that takes place? Most likely, 95% of your anxiety is over something that never comes to fruition. Anxiety can actually cause physical problems like nausea! For this reason, I would strongly recommend asking your doctor about anxiety medication
