Due to other system failures you have probably trashed that 'round encased' thing called a catalytic converter. Which , incedentally , is what the blinking check engine light was trying to warn you about! Recommend having it towed to a shop for proper diagnosis , more driving may cause more damage , resulting in more $$$$$$$$$$$$$$ gone.
