Always feeling like I

I feel like I've always been this socially anxious and quiet girl to new people. It takes me exceptionally long to make friends and can never open up to the fullest. I've recently started uni and I really wanted to change and be more open but I've just finished my first year and have come out with 0 friends. I have talked to a few people but I wouldn't necessarily call them friends, more like another person to follow on social media ygm. Everyone says join clubs and I've tried but as soon as I enter the room, I just have this feeling that everyone hates me. This sounds so dramatic and I just feel like no one really wants to talk to me and there's so many more interesting people in the room. I do have a stutter in certain situations and sometimes this puts me back from just talking about everything Cos I have to watch what I'm saying.
I just wanted to ask how can I take this feeling of not being wanted and how can I stop seeing this negative image of myself. I want to be able to make actual friends, instead of just having boring small talk with everyone.
I don't even know if any of this is making sense haha
