Tips on leaving parent’s house?

My mom NEVER let me go out as a child or sleep over at anyone’s house. I was a stay at home teen besides when I had to work or went out during the day. However, I always came back home. I’m leaving for college in a couple days, I’ll be staying in the dorms. I’m SOO not ready to leave the comfort of my room & my house but ig that’s how you grow up :( you’re just thrown out into the adult world wether you’ve prepared or not. How can I make it easier? Idk anyone there, it’s a huge campus & I get anxiety just by thinking about it. My bf will be joining me during spring semester but he’s in basic training atm
