How to deal with anxiety when I feel cornered

I notice that whenever I feel cornered, such as colleagues excluded me, working with people I am not close with, playing games but keep losing, doing things that are very difficult to get done, it makes me anxious and panic. So sometimes I try to avoid it, so I don't have to deal with them. I want to know how to deal with this, especially if it has something to do with work and daily life so I can become more confident and not run away from responsibility
