Ah exam stress, remember that well. For me, a turning point came at Uni when a lecturer took time to suggest to his class that we should approach the whole thing with a different state of mind.
Don't think of the exams as a test, think of them as an opportunity to demonstrate what you know, and if you've been doing your homework, you'll be surprised at what you do know. Ok, this is easy to say, but try it.
Remember too that you can undertake education at any time in your life and although it might seem like you've been building up to this for the last 4 or 5 years, it's not the end of the world if things don't turn out as well as you'd hoped.
And you're good at tests, you live with diabetes, RELAX!
Good luck, and welcome to the forums.
