Well first off I'd like to say that it's probably a good thing that you have an "overwhelming personality". (At least in my case assuming I am a PNM

) I remember when I rushed I was excited to go through but at the same time I felt very intimidated. The girls that stick out the most in my mind were the girls who made me laugh or complimented me. A laugh always cracks the ice and compliments make a person feel special. Really I think what would make me feel most comfortable would be to talk to an active member who seemed
genuinely interested and concerned about me. I think at first just talk to the girl about her feelings about rush and share your own stories. I know it always helped me to hear that an active was just as scared about joining a sorority! Just don't act fake. That's the most important advice I can give. I hope this has helped!
PPL,
