Only applying to one university?

I haven't spoke about the exact university in my personal statement, I've spoke about the subjects. It's the only university which has the subjects I want so I don't know how it would combine to other universities if I applied for those also?

clearing allows u apply to any course without your personal statement .but u need the grades

I've based all my personal statement on this university. But, now I'm having second thoughts on whether this is too risky. I've seen plenty of Universities I'm interested in however this is the only university which has the exact subjects I want to study combined. If I apply to other universities I don't know how my personal statement would link, for example a bit on my personal statement is speaking about crime / criminal justice and some university courses don't have that available with the other chosen subject I've chose.
What I want to know is, if I don't get into this University. Is it still possible to apply for others through UCAS clearing/extra and be able to adapt my Personal Statement for those chosen courses?
This is the closest University for me, and I don't really want to move away. Although, I don't feel the need to due to the University having the exact subjects I would like to study.

Also, has anyone else decide to stay at home and commute to uni? I don't really want to miss out on all the student life, but I don't feel the need to when I live 30mins drive. Just worried about making friends and fitting in!
