In college, I focused a lot of my time on working in a laboratory and studying with a difficult major. I also did have a close group of friends but I was far too committed to school.
It ends up working out, most people grow apart from college. It is a special time in your life, you are learning about who you are and what you like to do. Ultimately, in my opinion, it was far more important to me to learn how to work hard, solve complex problems and be resourceful than the social aspects.
If it is your last year, I would heavily recommend focusing on connections with staff, career services, other people who will be useful for getting a job, figuring out how to best apply all these skills you’ve learned into a career.
I was able to use a connection from a class to get into a job that led to the role I’ve been at happily for over a decade. So, definitely I would think about the future, connect with those around you, try to trust yourself that you’ll figure it out.
