I think someone hit the nail on the head in an earlier reply... it's the environment in which we work that can make the difference - especially for me...
I'm a research scientist - the job is good for me in that if I have a down day then I can take the back seat, pull away from people and work with whatever is in my test-tubes as opposed to dealing with people. On my better days I can speak to as many people as I want in my job.
Research is a brilliant place for someone like me, with my 'illness'. It gives me the depth to try things outside of the box when I'm feeling that I should try new things.
The difference for me is my managament, I used to be mananged by someone who made my condition much worse and I had a breakdwon under. My psych wrote a report and work placed me under new management. My new manager is fully aware of my condition and my needs and so I can have 'good' days or 'bad' days. He really is a diamond to work for - so much so I got him an award at work (financial) to let him know that I wouldn't be where I am today without him and his support.
So, all in all, research is a good area to look at as there are no set guidelines of what is expected - as any results are new.... AND also managment is another big thing to look for....
Gosh, rambled a bit there - hope it makes sense,
