in my experience, find a group of ppl or even just one person who has the same priorities and interests as you have. better if you are classmates/have the same course. it'll also be good in the long run especially if you need a partner or group for school works. y'all definitely be friends eventually. that's what i did and after almost 12 years after we graduate, here we are as adults and still best of friends ^^ good luck!
If you're in uni I recommend joining group chats and asking for study partners. If you're in high school, now is the time to join an extra curricular! Trust me. You'll form bonds and it'll still look good for applying to uni.
You can also join clubs and stuff at uni, but I get there's less free time in uni than hs. ALSO, not sure if you mean your school library or your community library but check what activities your community library has and join something sometimes. Mine has zumba, knitting, yoga, reading to kids, etc.
If you are in college or school just participate in extra curricular activities or volunteer works that place is filled with easy to friend with extroverts and it's good to widen to your contact circle. It's really not that hard you just have to take the initiative and they'll handle the rest. That's how it was for me.
pls give me tips on how to balance my school and social life. I have no social life in our campus bc im either studying at the library or studying at home. I always prioritize studying due to my very demanding course and many workloads. I barely even have friends pls help....
