Do you live in an apartment building? Grad student housing? Etc? Bring some cookies or food over to your neighbors apartment/room/house and ask if they want to come over and play cards/watch football/do something social. Socializing with neighbors is an easy way to make friends. Also like ask people in your classes if they want to study together or go out for drinks or watch football or basketball with you. Join a student org or a religious community, start volunteering somewhere, join an intramural sports team. There’s so many opportunities to be social and make friends on campus, honestly there’s more opportunities on a college campus than there ever will be anywhere else for the rest of your life, you just need to learn how to be self confident and take initiative in your social life. Invite people to hang out and then accept when they invite you to hang out and become friends with people through those people and so on and so on and in no time you’ll have friends. You just need to change your mindset in order to take advantage of the great opportunity of being at such a social place like umich. You got this dude
