new member of a sorority

First I would talk to your bid day buddy to ask them about their experience. Bid day is probably the most awkward day of the year, so it's normal to feel like you don't fit in when in reality, you don't know anyone!! If that doesn't work, talk to the president and recruitment chair. Maybe they can help!! Give it a few weeks and if you hate it then drop

Why didn't you feel comfortable there?

It takes more than a couple of days to feel a part of any group. For some it takes actually moving into the house and participating in work week to gel with the group. You are not alone.

Be proactive. Seek out other new members and invite them to walk with you to class/over to the house/sit with sisters in class. Go to the house as often as possible. Have your meals there. Sit with different people so you get to know lots of girls. Go to all the events planned. Volunteer to be on a committee. Make it work. It's up to you.
