It's normal to feel doubts. Did I pick the right sorority, major, college, etc.? I think that you should ask yourself why you think ABC or XYZ would be a better fit for you than your current sorority. Do you think that they are closer as sisters, nicer, cooler, they have more fun, a better fit? Whatever you feel is missing, you should try to bring out in your own sorority chapter. In order to have great sisters, you need to be a great sister. I really believe that you get out of your sorority what you put into it. Sisterhood needs to be nurtured in order to grow. I think that if you put forth the effort and have a positive attitude, your doubts will disappear.
