Loneliness is extremely common, I suffered it very badly in my first year, I'm an introvert but I'm definitely not awkward, weird or unsociable. But I made some mistakes which deepened the feeling of loneliness.
1. Comparing myself to others who seem to be making friends. This only made me more self-conscious and desperate. It made me think there was something wrong with me and that I was destined for loneliness going forward. In response to this, you're likely to make an even bigger mistake, this is to try to develop friendships with people, you don't really like, or respect that much, deep down. This has a long term negative effect on you. The friendship doesn't last and you'll have lost a load of emotional time/energy in that pursuit or if it does last its because you're sacrificing yourself throughout to hold the friendship together (e.g. if they always want to party, when you really need to study, then you sacrifice what's good for you (the study) for what's good for them (the partying).
If you see others "making friends", there's a chance of either they are lucky enough to have developed a good friendship with someone they like early on and have the same interests/compatible personality, or they are making the mistake that I have alluded to above. Every time you see "someone else making friends" you should fix your thought process, instead of:
"Oh look, they are making friends, I'm not, this means I'm a loser" you should instead flip this negative feeling in to a positive one and externalise it, believe me you'll feel much better, like think:
"Oh look, they're making friends, if it's a genuine one, that must feel really good to be in" and have a smile on your face thinking about it.
What you're doing here is you're not internalising it. See how there's no "I" or "I'm" in there and you're feeling a positive emotion, not a negative one. If you fix this thought process, then over the day, when the thought cycle repeats many many times, the sum total of that is a big difference to how you were feeling.
Now the truth is, people bunched together in halls of residences, you get a massive massive variation in personalities etc. It's very strange for everyone to suddenly make and be friends. If people do that it's because they feel they have to.
You need to increase your chances of compatibility by taking yourself out of your comfort zone and exploring other areas of the university. There's thousands of people at university. The best chances are:
1. Finding fellow people on your course, you can discuss your shared challenges on the course and through this get to know people - a big one is working alongside other people on the same assignment. For example, in seminars, get the contact info of your seminar mates, then when working on an assignment set for the next week, contact them for any ideas on it.
2. Unions - this is a big one, places which attract people that share the same interests or hobbys as you. These typically attract similar personalities who tend to find the same hobbies interesting. Again you have conversation opener based on the interest you're there for.
3. Sports - same above
Basically my point is, you have to continuously throw yourself outside of your comfort zone, in to these new areas and through them find and develop new friendships etc.
The loneliness won't pass on its own. You can continue to isolate yourself to your room, bury yourself in activities on the computer or in books that will distract you from the feelings of loneliness, but the loneliness won't go away. I promise you that and I'm talking from experience. That was the mistake I made and I'm telling you what would be the antidote to it so that University is by and large a genuinely broadening experience rather than a tortuous one!
Edit: FYI I'm 29 years old now, with a wife and 2 kids, talking about something I went through 10 years ago, but I've got some good perspective on it, sorry if my post is a bit insensitive to the Covid situation, I appreciate there are more barriers being thrown up (although I don't know exactly how its playing out for students in a university currently) I hope though you can take away some of the core principles and that I just want the best for you and fellow posters going through the same thing. Be kind to yourselves folks.
