George Michael just showed his face for the first time since being rushed to a Vienna hospital last month with a serious case of pneumonia -- telling reporters, the illness nearly killed him.

George spoke to reporters outside his London home this morning -- claiming, doctors spent "three weeks basically keeping me alive ... It was by far, the worst month of my life."

George choked up, insinuating he had been in a coma during his time in the ICU -- "I spent the last ten days since I woke up literally thanking people for saving my life."

GM was forced to cancel his European tour over the illness -- but promises to play several concerts to make up for it ... including a private concert just for the docs who saved his life.
