I recently got accepted into university after my A level results day. I've always wanted to change my name, but my parents for some reason were always against it due to its "religious meaning". I was bullied for it heavily as a kid and even though today I'm almost 18 and everyone has grown up, it still sticks with me. I also just never have liked it at all, so I grew up wanting to change it. I would love to change my name legally, but I don't want my family to find out at all about it because of the fights we'd get into and they would disrespect it a lot.
I was wondering if in uni, there is a way to change your name on lanyards and registers given to teachers n stuff whilst keeping my legal name in their admin and stuff? Like for example, giving yourself a display name on a videogame and changing the setting to make your username visible to only close friends or ppl you choose. I'm going to uni by myself so no one will know who I am, and I definitely won't give them my real name obviously, but it would be weird if I said for example, "hey my name is Alex" but my lanyard said my real name or the professor at the front said my real name for some reason (still don't know how uni lectures work). Any advice would be appreciated.
(Please do not try to convince me not to change my name.
This is a decision l've made for over a decade and I'm very sick of hearing it. Thank you)
