I have made friends in college without the help of a sorority! I've met people through class or through tinder or at house shows. Greek life is not the only way to make friends! There are many options and finding someone with common interests is the BEST way to make a friend.
I remember when I was a freshman at university and absolutely TERRIFIED of what was going to happen. I wasn't sure I would make any friends here, and I seriously debated joining a sorority in the hopes of finding a sisterhood of girls I belonged with. Deep down, I knew I wasn't the type of girl to be in a sorority (not that being in a sorority is a BAD thing), so I decided to try making friends the old fashioned way. Within the first couple of months, I had made some wonderful friends.
One of my newer friends at the time had invited me to a basketball game where we ended up meeting two really cool ladies, who became my first Eugene friends. None of us were involved in sororities, yet we still made our own friend circle.
My point is that you can make friends in college without being involved in Greek life! If you're not the kind of person who is going to do well in Greek life, try making friends another way. Maybe through some common interests!
I've made a lot of friends within the Eugene music community since house shows are where I spend the majority of my time. This exposure to the scene has helped me meet some incredible people and it's been HUGE in helping me make friends in college. Going to new shows and talking to new people has been the most effective way of me making friends outside of Greek life.
