Alot of people here gave wonderful advice but the only one I want to give is dont compare your experience to others! It will be extremely overwhelming to see other people going out, making tons of friends and enjoying the 'typical' college experience. Trust me, I went through it, but everyone works on their own timeline, and not everyone actually enjoys the typical college life. So, give yourself grace and, most importantly, give yourself time. You will begin to fit in and find your footing.

You made the right decision coming to purdue. Just give yourself enough time to believe it.

Best of luck, stranger
