Going to the disability office is a good start. Someone that understands you to at least bounce ideas off even if in the end they don't directly get involved.

If your lecturers know what you're going through, they have to accommodate as much as they can that works for the course criteria. Some students discuss this directly with a lecturer, some do it through the disability office (as they peeps know what they're doing, anti-stigma and can protect your details so you don't have to bare all to lecturers, they just trust the office knows it's legit.)

I saw mine to deal with a prick of a course I'm in now but the lecturer was quite an *** which I ranted about on here ages ago so won't now. :P I regret it now - I need less stress placed on me. It's my final year so it's hectic and I'm dying in it all.

At the moment, I'm starting to do all nighters and back on the caffeine. BAD IDEA. I feel horrible, now I can't do any study. I've always been unstable and I think I use to rely on mania to get my assignments done (poorly). Now that I'm medicated, I'm either sick or depressed so can't do anything! Sigh.

I've never got the balance right so I can't give your examples off experience though I'd have to say, getting it sorted asap is the main thing. If you know when you're assignments going to be due, set a few earlier deadlines to pace getting it done out to avoid not sleeping, using caffeine etc which could trigger an episode.

Also, you could always drop by to chat to a counselor at school? I know my uni has a number of them that most people use just to go over things like time management for this courses or how to organise their tasks. They might be a useful too when you don't have a chance to see your usual doc etc and they have the advantage of dealing with school related issues all the time.

In the end, if you get sick, it doesn't matter as far as school. Let your lecturers know and it's not the end of the world. They know you need to take care of your health above all. They'll sort out your assessment and anything else so there's not really isn't a big risk of a 'disaster'.
