Hi Cate. All I can recommend is to take deep breaths. The anxiety you are feeling is totally understandable as we go into fight or flight mode. Deep breathing helps to reduce the cortisol (stress hormone) that courses through our bodies when we have anxiety attacks. Also what about putting on some kick ass music as you drive home? I always like to belt out "let it go' from frozen at the tops of my lungs while driving if I am feeling anxious or am overly worrying about anything. It's so shitty we can't control the journey we are on. Wishing you all the best for your appointment tomorrow.
