You havent mentioned whether you are doing any after school activities?

Join any club where you can interact socially, like martial arts, boxing, any group sports, dancing.. or if not into that try chess/literature/board games/music clubs.

Not 100% guaranteed it will find you good friends, but you will get social interactions and be able to practice social skills.

This is maybe a bit of boomer advice, but if you are a young man you wont have many friends unless you can provide value to others, or unless they think they can get something out you, that something can be as little as social currency or being interesting to hang around with, which comes from skills and life experience.
