Hi Worried xgen
I am really sorry to hear about your situation. To be honest, I also had severe social anxiety throughout my adolescence which became an eating disorder and further worsened into generalized anxiety.
But I think you are a very courageous and brave person who is reaching out because when I was in my teens I was so embarrassed to tell my side of the story. So what I did was I simply started doing something for myself! Like I always wanted to be in the best shape of my life, after achieving that, I cured/reversed my eating disorder, anxiety, and fear of people!
Maybe once a week, have you thought of doing something just for yourself? It could be anything.
Other than that, I am always here for a chat!
