The mother of two, 42, wrote a heartbreaking tribute to her "sweet baby boy" in an Instagram post on Friday.
"My world is shattered into a million pieces," the philanthropist wrote. "I have little ability to breathe. Walk. Function. Sit. Stand. You were the light of my life. Your smile made the room so bright and your heart was the most perfect and sweetest."
McKee Zajfen continued, "You left this Earth and left behind so many people who loved you. I don't know how I'm able to go on. How I can function. How I can be the light and have joy ever again but I'm going to try."
The entrepreneur, who is also mom to nine-year-old daughter Lily with husband Julian, said she will "try hard for your beautiful twin sister."
"I can't comprehend any of it," she added.
McKee Zajfen also thanked her "world and tribe" for their support in "pulling me off the floor." She said, "I can't do it with you."
She concluded saying more details will follow including arrangements for George's funeral.
