Some background, my friend was really shy before high school, while during the freshmen year of high school, she tried to be really outgoing, meeting a lot of seemingly nice people eventually realizing they’re assholes, and closing off a little bit.   

A few days ago, she confided in me that she had been experiencing social anxiety again, (e.g. panic attacks and breakdowns) both in person and online. Is there anything I could to help other than just listening to her when she needs to vent or trying to help her slowly talk more people?
