I started having severe anxiety in 2016, lost a year of my life basically locked in my house. Slowly, I managed to get back outside and start doing things and now a couple years on, I am somewhat "anxiety free" (I still have a lot of anxiety but I am functional). 

The one annoying thing that hasn't really gone away is the nausea, especially when I am in a car or on a train/bus. Today I was in the back of a taxi and as soon as it started moving, I felt warm, dizzy and nauseas. I was actually thinking about putting the window down even though it was raining and cold, or even thinking I would need to tell the driver to pull over in case I was sick. Well, none of that happened, I arrived and was fine. Then I got a taxi back home and that was fine.

Yesterday I also had some nausea after eating breakfast. I went out to get a small breakfast/coffee before viewing an apartment and afterwards I felt sick. I thought I was going to have to stand outside because I felt so nauseas. Then I started worrying about how far from home I was and that if I did get sick, I would need to take the train home. A few minutes later, I was fine and got on with my day.

The thing is, when I feel nauseas, all of these negative thoughts fill my head and I start thinking such stupid scenarios. I have never actually been sick in public, so I don't know why I fear it so much. But these thoughts really have an affect on my mood and can ruin my whole day.
