Hey, I know this is probably not what you want to hear but I'm going to say it as bluntly as possible. Maybe the problem is you. And I don't mean that in a mean way, I just want you to change your perspective and perhaps realise that these things can be changed by you. As you said, "nobody cares much to help you", so you should try to help yourself. I'm going to give you advice that will hopefully help you.
1. Try to ignore the awkward looks you get from the girls in your house. And I mean full on ignore it, don't process it, don't think about it. And then start a conversation with them. It can be about anything, I'm 99% sure they won't shut you down. And I know putting yourself out there to like 5 girls in one go may be daunting so maybe try to get two of them on their own and then approach them. Or maybe even just one of them. Did you ever stop to think that they may not make an effort with you because you don't make an effort with them? They might think that you want to be left alone. If you still find this too difficult, maybe try drinking a bit (alcohol) and then approach them. Or propose that you all play a drinking game. Drinking will really help to stop you feeling awkward and worrying about what other people think.
2. In lectures, make an effort to ensure that you sit next to someone. Again, I'm 99% sure they won't mind. Pretty much everyone is the same when starting university: they won't know anyone and are dying to be accepted. Even if the person you sit with has found their place, they'll most likely know how you feel and be accepting.
3. Go out on your own to a nightclub or something and meet people there. If you don't speak to anyone, it's very unlikely you'll get a personal invite so you have to take it upon yourself to go out by yourself. Trust me, no one will notice that you've gone on your own and it's okay if you don't make new friends on the first night, but keep trying.
4. Search up about how to join societies and what societies are available. I know you said no info has been given, but really try to find out. It's probably the easiest way you'll make friends.
5. In pretty much every university I've looked at, they offer counselling services. So try to find out if your uni does and if they do, go. It will be helpful. You'll have someone to talk to and someone that can guide you and help you settle in. They'll be very used to that kinda thing.
6. It's only been a month, people may have made friends already but most people won't be entirely settled down into their friendship groups. Don't feel like it's too late to make friends, because it's not. You've just got to step out of your comfort zone and put yourself out there. It will be uncomfortable and awkward for a while, but I can promise you, you will be so thankful that you did it later.
7. Lastly, don't give up. As I said, it's only been a month, you're not the only person that hasn't settled down yet. Keep pushing through until at least February and if it's still a horrible experience by then, then maybe it's just not the right thing for you.
Sorry that I've gone on a lot, but I really hope this helps. Good luck!
