I think the big/little thing has become really overrated lately and I'm not sure why? I see it hyped up over social media.
Yes, sometimes she ends up being your
best friend but not all of the time (I'd say not even most of the time). I didn't connect with my "big" at all and we never even hung out. I bonded with my new member class and other older members instead. It wasn't a big deal though. I had a great "little" but she wasn't my
best friend although we were close. My best lifelong friends ended up being other girls in the chapter...and even women I've met as an alumna.
You have gotten some great advice on here. Just know that what you're feeling isn't uncommon. You will bond with other sisters
