Hair cut anxiety

I'm having my hair cut today. My stylist is lovely she even came to my ex and I's wedding. She is coming to my home so I don't have to visit a salon. So why am I still so anxious? I am having a drastic cut though from waist length hair to shoulder length. I don't know if it's the change that scares me or the fact that I haven't seen her for four years. Then I also have this excited feeling underneath the anxiety. I am trying to concentrate on that feeling. I've looked up how to style it and some inspiration for accessories too. I think I'm scared I won't be able to style it. I'm not the best with a curling wand 😂. I guess I will get plenty of practice and I do have one of those automatic curling gadgets too. Am I just being over paranoid? 🤔
