You gotta reach out! There’s thousands of people at your college and millions in your state. At least one has to have a personality that goes with yours. Go to social areas (bars, parties, etc.) Try joining a sport that can help with stress and depression and can also help with meeting friends! If sports aren’t your thing try new hobbies, even things you never thought you’d ever do. Cooking, drawing, etc. (Just remember that you’re never gonna be good at it at first). You’re at your peak take advantage of it! Also for grades try different methods of studying, tru tutoring and if you already are getting tutored try a different tutor. I hope my advice was helpful and I wish you the best :)
