On my campus we have a "Disability Services" office that I am registered through. I have accomadations so that I can take tests in a setting that has reduced distractions, extended testing time, etc. It helps greatly, considering that I have been newly diagnosed with ADD and am struggling with how to cope with it. I would look into seeing if your campus has this service available to you.
As for being Greek and having my disabilities, I recently was in our magazine,
Themis, about my struggles with depression and anxiety. It has been a long hard road, and one that not many can understand (including my sisters). But they love me anyways.

Time management is key here. If you can get that down, you will be way ahead of the game!!!
Good luck. Feel free to PM me if you need any more help or have any more questions!!!
