I'm in a heated room and wrapped up in blankets but im still shivering. What's going on?

sounds like you have a fever, try not to over heat your self as getting a very hot temp casn cause a seizure, drink plenty of water maybe take a couple of paracetamol to take your temperature down... seek medical advice if you do not feel any better

Sounds like you may have some fever.

You have a fever go take some ibuprofen or an anti-inflammatory and relax you need to drink some water and make sure you don't over heat,

Are you very thin? Did you eat or drink something cold? Did you eat at all today? Food intake and personal insulation can make a difference. Are you a smoker? That reduces your circulation and can make you feel cold. You could be sick. You could have just come in from outside and haven't warmed up yet. There are many possibilities. (you could be just having us on - that happens too)

Fever.

You will have a flu
