Community medical question

I have a severe headache and I am constantly feeling nauseous. Bright lights and screens are making my headache worse. Even after taking paracetamol or other painkillers, there has been no improvement. The noise of people speaking near me is very irritating, and I cannot focus on anything. Vision is blurr and my eyes are hurting so bad also tears coming from eyes... the headache feels like the worst headache of my life.
