how do I make new friends?

im a pretty shy and introverted person and almost all of my friends I've made in school but my friend group is falling apart and there are very few people I can tolerate in my class. anyways the one friend I've been able to keep in contact with outside of school is my best friend of almost 13 years now.

I feel like I need to go outside more and make new friends and have people to hang out with on the weekends and I wanna meet some boys outside of my class so things don't get awkward and unbearable to be around. I don't really like doing long distance relationships or friendships because I get grounded a lot and can text or call a lot.

back to my original point how can I make friends with out having to exchange a lot of my alone time and continue to be able to maintain it?

(also looking for a low maintenance friend to be able to vent and listen to here are a couple things I like musicals, Taylor swift, crocheting, and reading. I'm Brazilian and going to Brazil for Christmas. I do jujitsu and track competitively and I ski to)
