I understand what you are saying อีโมติคอนsmile It can be scary indeed to talk with boys if you have only other girls at your school. You can practice by talking to boys on the internet and when you have gained confidence in yourself you can try talk to other boys in real life.
I can show you what to look out for and you can always ask me for advice
Find a boy who likes you for who you are who treats you nice and doesn't force you to do things you don't like
