Annoyed with friend’s tension

Hi- I need help with a friend. Invited her and husband to beach, my happy place, she came in immediately the joy and leave changed. She was filled and is filled with stress and anxiety and wound so tight trying to control everything – and it drove me crazy. I was so frustrated and angry that I invited her, her child spoiled behavior drove me to overeat and snap and I could not control my thoughts mind and emotions. I kept trying the model – but how to feel the feeling of anger and frustration when you’re just annoyed with someone. I was so irritated about how her daughter’s behavior was affecting mine and how her behavior was affecting me. I knew better from coaching to change my thoughts, but it felt like resistance. And the dam broke. I just wanted to leave and change the circumstance. Help!!! How to feel the negative emotions surrounded by others?
