Freshers week is just a hype. I never went to any clubs or parties during Freshers, only went and joined a team sports club and met lots of lovely people. Plus, most of the people you meet during Freshers probably won't be the ones you'll stay friends for long. You'll meet people with common interests later downt the line, trust me! Don't worry and enjoy the feeling of this moment i.e. being a newbie in uni. Think positive!
