I have something similar at the moment. I first was thinking I was overworking myself, then I thought it was food poisoning or something, but it seems to be some kind of infection.

I’m slightly better now, but the past 3 days, I was basically bedridden. I couldn’t even make an appointment with the doctor or prepare food. I just can’t think anymore when I’m this sick. The physical discomfort is almost negligible compared to the inability to think and do anything anymore.
