Dez Bryant was posting through the pain during the Cowboys' shocking loss to the Packers on Sunday ... sharing his roller coaster of emotions on social media as his beloved team got booted from the playoffs.
The former All-Pro receiver was high on Dallas before kickoff ... saying he was "feeling EXTREMELY EXTREMELY great" about America's Team and claiming a $10,000 payday was on the line.
But things quickly went south for Dez ... as Green Bay came out strong with a 27-0 lead and never looked back.
