I am 31F, and have had social anxiety since childhood. In recent years I'm actively working on self- care and self worth with professional help and tools like "inner child work" which has been amazingly progressive for me. 
     My social anxiety has transitioned from feeling crappy about myself to worrying that people will treat me badly, or over -look my presence or not take me seriously, all of which were previous experiences. 
      I'm still learning to respond to these situations, and struggle to stand up for myself or be assertive or tell people, especially friends, to be more respectful. 
     I have had to let go of a lot of childhood friends who are not able to make that transition and see me for who i am now, their behaviour has not changed, and it makes my anxiety hit the roof. Therapy has helped in letting go of these people who you sometimes build a big part of your life and identity around. 
      Anybody having similar experiences? How do you respond to people in these types of situations?
