Do you have anyone you can contact professionally about this? Also, how severe is your diagnosis? My girlfriend suffers from moderate austism and has similar reactions when faced with large amounts of information, and part of her coping mechanism is work; she gets very easily overwhelmed if she's sat around doing nothing and when she got less hours at work, but now that she's regularly working and occupying her time, she's coped much better. She's done quite well, considering that her family not only gave her no support for her condition, at home or through doctors and they even hid her condition from her for a large portion of her life.
I can't imagine what you're going through. I don't have the condition myself, and after being out of education for a good eight years, I can sympathize; the amount of information I had to get when applying for university, student finance and such was ridiculous. My university had a drop in center, even for non-students, who can help walk you through the process or give you the information you need for certain parts of your application.
All I can say is, like with any diagnosis of a constant condition, don't pressure yourself too hard to cope. A year is relatively short when you think about it, so putting a huge pressure on yourself to adapt to a change in your life isn't going to help. Hopefully, you can get in contact with some help groups, either in your community or online with people who can help you get an idea on what works for you as a coping mechanism.
