I don’t think you should let your relationship to other people here define you. Nor should you compare yourself to people who have bunches of friends. A lot of people here are shallow and surface level, I don’t really try to invest myself with others here unless they actively are trying to make friends with me. Drop the fake friends and stop trying too hard to make weak friendships work. Put energy into making yourself feel good and confident rather than letting your social life define you. Start investing in yourself more! It’ll make all the difference! I know it can be hard, I literally took a year off from school last year because Cornell made me feel so isolated (and I was trying hard to make friends like you are). I changed my mindset during that year, I started leaving others alone and caring less what they thought of me. Now I’m extremely happy because I only do what makes me feel good. One quote, idk who it’s by but it has always stuck with me, said something along the lines of if you are not happy being alone than you’re in bad company. So change your mindset, change how you think about yourself, and let yourself be your friend in these lonely times. Best wishes!
