It's the exam and anxiety in general. I know it might be silly but I'm super anxious about this exam and I'm very afraid of failing. I spent so much time studying for the oral examination that I haven't had time to study for the final exam, which is on Friday. So now I'm awfully stressed and I have no idea how I'm going to learn everything in the days left until the exam. I'm incredibly afraid of failure (which you might already know) and I'm catastrophizing. Even though I know that's what I'm doing I can't seem to stop it. Instead the anxiety is "spreading" and I'm getting really anxious about a lot of things (but mainly the exam). I'm so exhausted and stressed and anxious that I can barely focus, I can barely sit still and I'm almost feeling physically sick. I just want to curl up into a ball and hide. Not exaggerating. And I hate myself for complaining so much.

EDIT: I'm quite bad at multitasking (I want/need to understand everything so I only focus on one thing at a time), which is why I didn't study for the final exam the same time as studying for the oral exam. I also find it incredibly difficult knowing what's important when it comes to the information in the textbooks etc. I'm not stupid, I just get overloaded.

Also, thanks for caring (I'm honestly surprised you haven't thrown me out of the couch by now).
