It's definitely worth trying, and I commend your bravery in facing the unknown. I was the same way when I started about 5 years ago, and now I'm a dropout with no degree, no friends, and feeling much worse than I did when I started. I tell you this to serve as a warning, not to scare you. Here's some advice you may or may not find useful so you don't end up like I did.
First, don't live in fear. It's too easy to simply go from class back to your dorm/apartment and avoid others, and repeat the this process everyday. Whatever you do avoid falling into this trap no matter how tempting it is and your mind tells you to. Join clubs, do your homework on campus, invite clasmmates to study/grab something to eat, anything that will potentially benefit you in the long run. Just at all costs do not isolate yourself despite how much you may want to.
Second, avoid the sunk cost fallacy. This goes for your friends, clubs, major, or even school. If you get bad vibes from something, move on and find something better. I stuck with the first friends I met, and the first clubs I joined despite all the signs of them not being good for me/valuing me, and it eventually came back to bite me and left me with nothing. Also if your university feels like a bad fit, transfer the following semester to somewhere else and don't look back. My first school was extremely cliquey and Greek-life focused, and I clearly didn't fit in but I stayed for years trying to force it due to sunk cost fallacy, and missed out on potentially going to somewhere that fit me much better.
Third, don't focus on romantic relationships, and prioritize yourself. I got into a relationship with someone early on and gave so much time to her, only for her to leave me at the end for someone better. All that time I gave to a relationship I could've used to better myself and my future. Now its gone and I'll never get it back, and I got nothing out of it. I do think you can make a relationship work while in school, but no matter what do not prioritize it over anything important and non-relationship related.
I really believe you can make this work and find what you're looking for. You might not find this advice useful but if someone told this to me when I started I'd probably be in a much better place. Maybe I'd have the life I want and I wouldn't even feel the need to visit this site. Good luck and I wish you the best.
