One thing that people need to realise that you can use your body to trick your mind into doing things. If your brain is anxious, you can consciously use breathing techniques to trick it into thinking you're calm. Box Breathing for example works pretty well. Or just taking 2-3 really deep slow breaths. An anxious/nervous brain defaults to short shallow breaths for some reason.
