Hi. I'm currently in third year at York University and have found myself going through the same thing for the past few years. I myself am introverted and struggle to start conversations and form friendships. It was particularly hard as most of my flatmates had friends from college and secondary schools at the university with them whereas I knew no one. However, I decided last year to go against my comfort zone and attend a society just so that I'd interact with others and get out of my bedroom for a little bit. As I'm quite a nerd, I ended up going the Harry Potter society at my university and while I didn't form any really strong friendships, I still found people to talk with and enjoyed a couple of hours each week away from my room and my uni work. From this, I then created a time table for myself whereby I prioritised my work load but also allowed time to just go on a walk, go to Harry Potter society, have something to eat or even watch YouTube (the Sidemen in my case) just to have that little bit of stress free time to calm myself down. I don't know if this could help in your situation as I don't know if there are any societies at your university that you might be interested in or if timetabling specific activities would help you. As for the extractor fan, I also had trouble sleeping in my first year due to a lot of loud people living in my flat. I found that for me, I was able to sleep easier when I had a YouTube video of some music in the background on a low volume as some buffer noise in the background.i Know that some of these ideas may not work for you but these are just some of the things that have helped improved my lonely and stressful time at university and I wanted to share them with you to see if they could help you in any way. I hope whatever happens, that the situation improves for you.
