It sounds to me like you're just having normal pre-test stress. It's very common. Ask yourself these questions:
*Did I teach what I was supposed to this year?
*Did I reteach anything the majority of the students didn't understand?
If you can answer yes to those, then you've done what you could. Don't let the state test stress you out. When it comes down to it, you've done your job. The kids have to step up and do their part now. We can't take the test for them. Do some review in the weeks leading up to the test, and then resign yourself to the fact that they're as ready as they're going to be.
