Ironically, I did this very same thing with my sister/friend. My in-laws were visiting and I have terrible social anxiety. Worse yet, I was left alone for the day with them. I wanted my sister to meet us for dinner for support, but she doesn't like them either and made up an excuse. I got hurt, felt out of control because of my mounting anxiety, my low self-esteem kicked in and took over. I pushed her away (figuratively).
