what am I doing wrong?

Seriously? I have arrived as a fresher and have met people. I have met no one that I can say I have clicked with. I dunno what to do an am scared I will spend the next few years alone.

Arrange an impromptu party in a corridor somewhere in your block with whoever you get chatting with. Make a few posters and stick them up around the place, something like "come back to the courtyard after the 60's ent on Saturday, bring some booze and whatever music you like", or if someone else is having one, go along and chat with people. The more people you talk to, the more likely you are to find someone you click with. Don't worry about not having clicked yet, you've only been there a few days and it's all rather hectic - most of the people I was "friends" with in the first couple of days I hardly talk to now, but we've found people we just like more, nothing malicious, it's just the way things go. Most importantly, relax, have a good time, and be yourself - the three things which will endear you to people (unless "being yourself" means "being a cantankerous old sod", which I'm sure it doesn't ).

Spend all of your time drunk.
