Oh my word. This child is me, when I was young. Bookish, putting herself out there with limited success, too anxious to talk to my existing friends, let alone make new ones, etc. It was hard to live through, and I feel for your daughter.
Here’s food for thought: into adulthood, I would make up excuses when I had to leave a social engagement. A socially skilled roommate called me on it once, and taught me the phrase, “ This has been great.” It seems like such a small thing now, but at the time it was a revelation. It has freed me from so much social anxiety to be able to leave a party after I ran out of people to talk to. As an adult, I would kill for a PEERS class, and I would have welcomed it as a kid, as long as my friends and classmates didn’t know. Coaching from a therapist might also work, if you need insurance to afford this. She might qualify under an anxiety diagnosis. Ask your pediatrician for recommendations.
The well-intentioned “find her people” advice is not something I would advocate. I found my people eventually, but the years of waiting in the meantime was torture. Moreover, over-reliance on a few friends taxed those relationships more than was fair.
