I'm going into third year and my main worry was not making friends... everyone i know has made friends and looking back now i realise any worries i had seemed pointless by the first term.
everyone will have a great time! there's a really good book called "A Guide to University by Actual Students" on amazon for £1 and it goes through everything in first year: money, overdraft, relationships, freshers week and making friends etc. so check it out if you have any worries, it's fairly recent so very updated and modern
