There are a lot of bugs about ATM. Sorry you have felt ill all week. And that it's at its worst at Christmas.
It's easy to say. But sometimes it's easier to get through an unpleasant situation if we accept it's happening, rather than try to battle against it. Sometimes that can help to break the cycle of anxiety.
And there are some good apps around that help you change your mind-set where you can follow guided imagery to help calm you down. Aura is meant to be good but I haven't tried it myself.
Also, probably unhelpful to say this ATM, as I know from personal experience that it's not at all easy to do in the moment, but maybe you could start to consider this as an opportunity or catalyst so that you can get some support with your anxiety so you can model to your daughter that although a bug is unpleasant, it is part of life and you will get through it fine. As a pp said, without minimising what you are feeling, sometimes the fear of something is worse than the reality.
This page on the Mind website has some useful exercises:
