Sorry about the allergies and the dogs - maybe some people require more information about allergies - so that they would have better understanding about the symptoms and problems. At the sorority - you want to keep your housing right now, and find yourself among others who are yelling at each other and angry at you. Would it be helpful to show them a chart of your schedule - so they have better understanding of your time obligations? And point out to them the events that you can attend. I'm not sure what their expectations are, nor what your obligations are? With the unpleasantness of that sorority atmosphere - what might be some possible alternatives? Be clear in your mind about your priorities.
