worried i have diabetes/anemia

You mean a big, life changing event, but it's okay to put off for a month or so? Sounds unreasonable, but it's about the norm. If the results show you have diabetes, you've probably had it for several years, and another month more or less isn't going to make much difference. If that's what it is, and if your case is extremely advanced, they would probably get you in a lot sooner, at least if you are in the U.S.

Don't get upset. If that's what it is, just finding out and taking charge of it puts you ahead of a great many who also have the disease. I can't tell you a thing about anemia, but judging from the way they are scheduling you, it's probably something else that needs attention but nothing to panic over.

I would start with looking for a new doctor. If it is not that serious then they can tell you over the phone...making you wait a month is cruel.

I agree. I would also ask for a copy of the test results. If you don't understand it, there are websites that offer explanations of the meanings of blood test results. You can also ask here. We have many folks on this site who are all too familiar with blood tests.

It is ridiculous for you to have to wait a month to learn what the tests found.
