I think I’m older than you and I have my group of friends that I’ve been friends with for years, so it’s a little different, but when I was 14 & at school, if I felt too shy, then I would ask a close friend to have a small get together at her house and ask her to invite my crush! Then we would play board games all together and get to know each other better. Then maybe I would suggest we all go out bowling another day etc. During these events, you can discover your common interests/ hobbies etc. the secret is to be yourself and try to get to know them. There will always be friendships and relationships that don’t work out but the more honest you are to others about who you are and what your interests are, the more likely you are to attract and click with someone who gets and appreciates you. Above all, have fun exploring this stage in your life 🤩
