Urgent,whilst i cook eggs,pork and other stuff in a stainless steel pan it burns why?

[Wayne Starleigh]

Hey,
As you read,my pan's burns alot while i cook and at the moment my pork is burnt but when cutting the meat, it was still raw.
I also have a problems with fried eggs, i let the oil cook for a bit and then place my eggs in. However it sticks to the pan and burns the pan too. How can i reslove this as my pans are getting ruined and my food aswell.

Thanks
