Hi there
I am the mum of a Uni student and just felt the need to reply.Things will get better; you will not be the only person feeling this way and you WILL meet people.You say people haven't invited you to societies...well just turn up on your own, it is not too late !There will be lots of people there alone not everyone will be in a clique, just keep turning up to events, even if at first it seems strange and you are on your own.Dont try to force conversation too much, but be a good listener...most people like to talk about themselves, so show an interest and let them talk!If people have problems..just listen, dont advise!Be the one that is there for people.
Have a few 'stock' questions..'where are you from?' 'What course are you doing'...but dont stress too much about chatting.The world is full of talkers..but they also need an equal number of listeners..,.make sure you are a good one; maintain eye contact, have an 'open ' posture , breathe.........and relax!!
Do you have the opportunity to do any volunteering?You can meet people and have something to put on a CV .Join a gym...get fit and meet people (even if it is just chatting for the hour you are there),
Don't rely on your best friend ..he will be making a life for himself and he wont be intentionally ignoring you ....look forward to seeing him at xmas.
Make a study timetable...and stick to it, read study skills books that will help you , revise as you go along, tick things off as you achieve them, visit the library and read around your subject ..you WILL meet people there too !Are there any small tutorial groups you can join?
It might be a good idea to speak to student services and your GP..they will have lots to offer you as they will have seen it all before.
Good luck ..I KNOW things will get better
