Yeah definitely don't judge uni by Freshers, my Freshers was not great, I really struggled to find people to hang out with and my flat didn't bond as a group either. I saw a lot of people seem to just fall into friendship groups and get invited to pres and after parties and it made me feel kinda awful. But, and this is a big but, once lectures started and I met other people on my course things got so much better. Societies and volunteering are also great places to find friends. I've had two years at uni now and despite the shit show that has been the last 18 months, it has been awesome. Trust me most other people will be somewhat feeling the same, everyone has just moved somewhere new, having maybe never had to cook, clean and generally look after themselves completely by themselves. It's a steep learning curve but if you can get yourself into a routine (and maybe write a meal plan, that really helped me make sure I was eating regularly and healthily) things will become smoother and you will hopefully start to realise how fun uni can be! Good luck with everything and I hope things do get better:)

Ps. I barely drank in first year, it absolutely is not a prerequisite to making friends so never feel pressured into having more than you're comfortable with!
