How do you make friends?

This probably sounds very weird but I'm really confused how to go about it. I see everyone with their friends or circles and I'm baffled how people find others that match their vibe. For starters I'm 18 F and recently shifted from a reputable college to an English Medium school nearby due to some issues. Since it's EM there's just 2-3 people in my class and even they aren't too regular. I was wondering since most people make friends in a school or college setting, how do you make friends in Dhaka without that kind of place? I do have a close friend but she recently got into a relationship and is a bit on the extrovert side so she has her own thing going on. I also have a strict mother. I've been a super introverted person throughout my life and it's only now this void-like emptiness is really hitting me. I love art, music, writing, studying but everything just seems to be boring now. I've also kind of felt like a third-wheel in everything which doesn't really help. I just really wish I had an awesome friend group or just someone to hang out with and have fun sometimes. I'm really lost with my life and kind of been living in my head for months so any advice would be very appreciated!
