Woke up and got a fking fever out of nowhere. My vision delays when i turn my head while walking, feeling unstable physically, brain feels like its melting, headache, im hot and have high temperature, burning from inside and at one point i started hallucinating the more movement i made, literally saw someone walking in front of my bedroom while no one was there. And then started seeing circles triangles and square shapes in my vision but for a short period of time. I live with my parents

Wtf is this???? Did i experience mental burnout from excess stress and studying???
