It’s completely okay to feel like this, I think people massively underestimate how torn you become between uni and home, especially if home is far away and you still have strong friends and family. But you’re allowed to live your new life and you’re allowed to do it guilt-free. It is incredibly difficult to like you need to please everyone and attend to everything constantly. Nonetheless, my advice is to set up a weekly schedule or little meeting with your friends and family from home to have a catch-up or have a little gossip. By having a set time each week to catch up you can reassure yourself that you're putting time aside for them; as well as reassuring them that you're still present in their lives.
Similarly, you could also invite your home friends up to uni to come to stay - I know it seems a bit daunting to mix your home and uni life but a night out in Market Shaker is definitely the best ice breaker you can possibly have.
I can promise you now it'll get easier, even if it feels stressful right now but remember it is YOUR life and no one else can tell you how to live it.
Good luck - god gives his hardest battles to his strongest soldiers. But in all seriousness, it is not the most pleasurable of activities having to sit through 90 minutes of a football not knowing who you actually want to win. However, at the end of the day, it is their problem; I can understand that football is their passion and it will be important to them but the world will keep turning no matter who wins or loses. It’s already brilliant that you show up and support your friend's interests; I’m sure it means the world to them that you’re willing to even watch with them, no matter who wins or loses.
