Prednisone and type 2

I have been sick for about 3 weeks and finally decided I had to be seen. The doctor put me on prednisone because she said that pros outweigh the cons as I caught adult croup (from my sick kid). My blood sugar is 354. My anxiety is terrible as I am super sensitive to steroids. I will call my primary tomorrow morning. I am on januvia. I don't know at what point I need to go to the ER if it gets worse. I know that at type 2 I am not likely to go into DKA. I don't think I can just up my meds because they aren't insulin. I think I am just freaking out because steroids + anxiety disorder + high blood sugar = panic. I am drinking tons of water and having high protein meals and snacks. Is there anything more I can do before talking to my doctor in the morning?
