Just to offer some perspective, I'm starting my PGDE at Edinburgh this year, having already done my undergraduate and masters back in England a few years ago. I am commuting from Glasgow so will not even be based in Edinburgh and I can assure you that as someone who is very keen to have an active social life at university, I am not at all worried. Having previously gone to university in a new city, knowing no one, this is exactly what societies, course social events, etc. are there for. I am personally looking forward to meeting my coursemates but I am aware they are essentially a random sample; societies and sports clubs give you the chance to meet people who already are guaranteed to have a shared interest/hobby. Depending on your course, you may also be very likely to meet like minded people. From experience of going through university during COVID and working in a job where work from home is common and in a way encouraged, it's absolutely on you to take advantage of the social opportunities. Don't rot at home and watch your lectures online (I've made this mistake), get up everyday, get dressed and make yourself feel good and go out, whether it's to lectures or just to the library to study. Your home is for relaxing and leisure not for study or work—and the only way you can guarantee yourself to not meet anyone or have any new experiences is to spend the day at home. Put yourself out there and feel good about yourself and your efforts will pay off. Feel free to message me ☺️
