It'll all work out - as elisabeth was saying - the time will fly by, and as others have suggested, the fact that you aren't being rushed in there immediately means it's not likely to be anything too scary.
That said, I know the 'not knowing' part is anxiety-inducing. My best suggestion is to assume the best - thinking that it's a good thing that you're getting to the bottom of things, and will very likely end up with some real solutions and healing.
