I have 2 daughters in years 9&10z
Younger was in sociable and has friends older one not so much.
She had friends but as they get older said friends want to be going out socialising /boys etc, my DD Is happy at home with a book!
She still has these people to stand with at school but that’s where it ends.
She relies heavily on my younger daughter at times which even though they clash at times.
I keep reminding my daughter she has about 18 month left at that school and will fly over but she is so sad and depressed. I cry myself to sleep about it sometimes 😞
