Not to say that this video even begins to cover everything RSD means, it did help some people gain a bit more insight into what I go through:

http://www.youtube.com/watch?v=luQKgR6iWy8 <-- not sure if I did that right, or if its okay that I posted it - so if it doesnt show here go to youtube, search RSD Awareness and find the video titled 'What if...' I've watched a lot of awareness videos, but this one is one of my favs. I've had people that I've spent a lot of time trying to explain what I go through to yet I know they didnt even begin to grasp it, because when I posted this video on facebook I had so many of them shocked, upset, and very suddenly wanting to help me in anyway they can! Although the video doesnt say anything I havent said! Kinda weird! Good luck!
