I hope you can find something that helps you reduce your stress and anxiety. I've been having depression/anxiety issues since I was 10, and was officially diagnosed at 14. All through my life it's been my pets who have made the biggest difference for me, no matter what they always make me feel better. It's too bad you can't take a pet to an exam, being able to pat a hedgie might help keep the pressure from getting to be too much. ^_^
