I shot the ball before the buzzer, it went in after the buzzer. Would this shot be counted?

Here's what happened. Its was under 2 seconds left on the clock. the score is 76-74, the opponent is up by 2. my team have no timeouts left. the opponent is shooting his 2nd free throw attempt. He missed on purpose. I grab the rebound and just lobbed right away from full court before the buzzer sound. buzzer sound came out while the ball is in the air and then the ball hit the floor and bounced once and then went in the basket. Should this shot be counted?
