I had to read a couple of books about teen girl psychology to understand just how badly teen girls bully and mistreat each other. It was a real eye-opener.

But then the bullying never really goes away for either gender. It's disguised and legitimised as various commercial, professional, political, and social activities, but the motivations are similar - just more covert.

Though some people continue bullying into adulthood, many of us have more control of our situations as we grow older, and in we can often avoid situations where we will be bullied. Students usually have so little control of their situation that they are really stuck and can't get away from bullies. School can be a special kind of hell if you don't fit in and can't get away.

But it is not like every single female group had massive bullying problem. Just like there are plenty of boy groups who don't bully each other.

This is like saying "I had no idea how severely boys beat or insult each other". It is absolutely true that such problem exists among boys. But you still have a lot of groups where boys don't beat each other.

If anyone is looking for how interaction between teen girls look like, this parody made by The Onion is the best depiction I've ever seen: https://youtu.be/XUT8ec24anM

What books if I might ask?

Still, girls need more social interactions than boys in general, as the mental issues are different.

According to other research boys are coping mentally better with COVID than girls.

Then again, boys had more social interactions during lockdown due to online gaming being way more prevalent among boys. For many boys, they kept gaming and thus socializing largely as before. Girls social was more in person or composed of general "keeping in touch" and not much was happening to talk about.

I purposefully shown some online games to my daughters so they can socialize with friends. But looking around, it was quite exceptional move for parent of girls. They had more schoolmate boys playing with them although they normally socialize more with girls. And some of those girls were the ones I told the parents about the option. I did not asked single boy to join, they were already gaming.
