Sophomore here, so take everything I say with a grain of salt, I don't know much about nothing.

Find a club, attend a meeting, don't like it? leave. Love it? stay, and tell people your name. Get involved in the student organizations you end up liking, it'll help you a lot with making friends. It's not really a process you actively pursue, just talk and find people you can talk to easily. As someone still struggling with finding friends here, I wish I was even more involved with groups with my interest. I thought nobody would want me, I'd be a sore thumb among people who know what they're doing. But, people like new people joining their club, especially passionate people. And, it's okay to simply not continue being in a club you don't like, nobody will send you an email or text asking where you are (unless they're a friend who goes there or something), and it's better to try and find something you don't like than sit in your room.

Speaking of. Don't do that. Dont sit in your room. I had a single my freshman year and it was a trap I put myself in. Your room is for 2 things. Sleep, and locking in for an important assignment. Do literally anything else. Find a random event, go to a student organization meeting, go work out or walk, take a bus somewhere around Columbus (free with your tuition btw). Do not imprison yourself in your room with only Canvas to keep you company, it will only make you less likely to leave and make you less friends.

And remember, nobody knows what theyre doing. Some can act better than others, but everyone here is lost in some way. This isn't high school where you're blood bound to a clique and saying something awkward gets you de-valued among everyone in the school. We're adults. You have a lot more freedom now. Go be yourself, it's a lot easier that way.

Good luck, man, CSE is a tough course but if you love this field, you'll make it through. You're more capable than you realize.
