Well, I'm six weeks into my PhD program and my whole mood has changed. I am very angry and anxious to the point meds won't work. I honestly don't usually have a problem with anger- so this symptom is new to me. I wonder if my new environment has triggered this anger and heightened anxiety. Sure, there's an adjustment period; but I know how to be a graduate student! Also, I have been followed to my apartment twice and that has put my anxiety through the roof... but that doesn't explain the anger.
