Making new friends can seem daunting but at Freshers' Week, remember that everyone is in the same position as you. They're all feeling a little anxious and out of their comfort zone, so be bold, don your lucky Spiderman undies (or pack your good luck charm) and make the first move!
It's easier than it sounds - go along to as many social events as you can and try smiling at everyone you come across (as unnatural as it may feel). More often than not, the other students will be relieved to see a friendly face, you'll exchange pleasantries and then you've made your first friend. Simple.
