I have a hard time making new friends at uni as an international student

I am 18F, studying in Amsterdam and even though half of the year has passed, I have managed to barely make 2 friends. I really want a larger friend group, preferably multicultural as it will add tl my experience of studying at a diverse uni. However, I cannot bring myself to initiate friendships and feel really lost when it comes on how to make friends. Some advice would really be appreciated:)
