I've got an older sister and friends who are 1st and 2nd year students, and from their experiences, people normally get really involved with uni life (and there's a lot of stuff to get involved with at Sheffield Uni!) and sure they go home but not as often as every few weeks. However, in my own case, (I'm in Y13,) I struggle more with mental health stuff and transitions, so I'm staying more local to my family, and luckily my first choice uni is practically on my doorstep! I've got a friend who is staying within about one hour of home for personal reasons. Some of my friends are rejecting their local unis simpily because they want to move away from home. That's also fine, it's just about whatever is right for you. Not being at home for every weekend doesn't mean that you're by yourself. You can call, text, facetime, etc, your family and your pets, and there's plenty of support at unis for moving away from home, being independent and settling in because most of the 1st year students will be in the same position as you. Try to weigh up these differernt factors in your decicion, if that would help you
