Hi Blue. I'm sorry you have this problem. I have school anxiety too for many years (luckily not at university), so I understand. But, I think it would be good for you to try to go...your meds could help, and also trying to think that when you arrive there it gets better (it happens also to me, my anxiety is especially before doing things or going to places). Also, trying to identify what exactly gives you anxiety (getting outised home? meeting people? something else?) and working on it.
Wish you good luck
