This is so embarrassing but I need some help 😣

I’m so embarrassed but I am in my early 20’s and have no idea how to make friends! 🤦🏽‍♀️ I have been working at a hospital for the past 3 months and I just haven’t connected with anyone. I mean everyone kind of talks to each other but then you see those people who actually become/are good friends and I litterly have no idea how. How do you turn that small talk into friendship? Other than asking them to hang out bc some of the people I would like to be friends with don’t know me that well and I feel like it would be too soon. Iv always been pretty shy and unintentionally to myself but I’m really trying to break out of my shell, I just don’t know how! Anybody know how I can make some friends? Iv kind of gotten past the being shy to talk to people now I just have no clue what to say! 🙄😩🤦🏽‍♀️
