i don't seem to have a place in my chapter, advice?

I know how you're feeling, I had this issue too when I first joined my chapter because I can be kind of shy and introverted. I never got close to my pledge class because I hung out with my big and her friends all the time, but they were seniors and so when they graduated I felt alone because I didn't know my other sisters as well. What really helped me was taking a little! When you take a little you become their rock and a guide to the chapter. You're the first person they'll turn to for advice, the first person they'll invite to study or go out. Thanks to my little I have a new best friend in the chapter and I've also grown closer with her pledge sisters and mine! It really does make a difference :)
