Hello there! First of all, I am really sorry it took me so long to reply to this thread, I have just seen this! Secondly, I just wanted to chime in with my personal experience at Keele. I am an international student (from Sri Lanka) and I am a 2nd year Physics with Astrophysics student.
I would like to start off by saying that your question is totally valid. I understand the pressure that comes with being far away from home for university but also having to worry about not fitting in because you come from a different background. I understand how things like your friends not being able to pronounce your name, leading to your entire identity being compromised, or the little things like people's comments on how you say things, all add up to you feeling like you stick out from the rest and don't belong.
I was really worried about the same things you are worried about right now, before I started at Keele and to be completely honest, I still am to some extent. However, I am really glad to say that Keele is a lot more diverse than I thought it was going to be. My class has a fairly even split between ethnicities and nationalities just like my colleague mentioned. I also joined the cheerleading team in my first year and tried out basketball in my second year and I am glad to say that both of those clubs were really diverse.
I am not going to lie to you, you will have brief moments when feel like you will not belong, which is why the friends you make at university will be so important. When you do go through rough times, your friends will be the ones who will help you realise that you are part of the group and help you move past any negative feelings. For example, I lived in university accommodation in my first year and I lived in a flat with two English girls (who I will be sharing a house with next year), a girl from Egypt (who I am still really great friends with and miss so much) and three boys from Kuwait, Cyprus and China. So our flat itself was really diverse! More importantly, we would always talk about what it was like to be from different countries, cultures and ethnicities. I personally found it comforting to know that we all cared enough to talk about our differences and it made us respect each others beliefs and cultures even if they are different from our own. Us girls especially were really close. We would often spend our nights sipping tea and talking about various things for hours before we went to bed!
Like I mentioned before, Keele still isn't perfect but at Keele, we regard diversity in terms of ethnic and racial diversity, sexual orientation, gender identity, physical disability, neurodiversity, diversity in gender and more. The statistics alone are not important to us, what is important is creating a culture where everyone can respect each other, no matter their differences and I think that Keele is very transparent about these issues and continually working on them. Looking back at my two years at Keele and also taking into account the response that the university and the students union has had in relation to the black lives matter movement, I genuinely believe that Keele are working towards increasing diversity in all these areas and trying to make sure that every student will have the best experience at university.
Sorry about the really long response but I hope this helps ease your nerves a bit. If you have any questions, please don't hesitate to ask!
