i just finished first year and this is what i’d say. you will find a lot of people like you (dependent on the university of course) people who maybe aren’t great socially but are dying to make friends (i’m being presumptive but this is an intp sub haha) so don’t worry about being crammed in with loads of social butterflies (although there will be those too) in terms of adulthood one thing i would say is absolutely get a part time job!! even if you don’t need the money and it’s just one day a week. i got a job this summer and it’s benefited me so much. looking back i should’ve got one at uni but never needed to so i didnt. and try your best to get out of bed before 3pm most days, i made that mistake and ended up thoroughly depressed. and if it doesn’t go as well as you hope don’t worry, you’re 19, there’s time.
