Hello there, I am Maristella. I study in Coventry University and I am more than happy to give you a different perspective on this.
It sounds like an incredibly challenging situation, and, understandably, you're feeling a pull in different directions. It takes a lot of maturity to recognise that your current university isn't providing the right academic challenge or, more importantly, the level of support you need. I can imagine how disappointing this lack of understanding from your tutor is.
You've clearly identified what makes you happy: the independence and the friendly, vibrant environment you found up North or in the Midlands, where you already have a network of friends.
While your grandmother's offer comes from a place of love, and I totally get how you feel, I believe it is important to remember that this is your degree, and your best chance of succeeding is to be in an environment where you feel genuinely supported and engaged.
I'd definitely encourage you to explore the options that are more appealing to you while considering potential challenges and maybe make a list of Pros and Cons for each scenario 😎.
In general, maybe finding a place where you can keep your independence and be closer to people you connect with will be invaluable, and a heart-to-heart with your grandmother, explaining that whatever choice you make is essential for your future success, should help.
Ultimately, the best decision is the one that makes you happiest and puts you in the strongest position to thrive!
Good luck 😃
