My first thought was that this was a flopped straight or set that decided to quit screwing around when the board double-flushdrawed. My 2nd thought is that you have no redraws to a made straight and that you should fold.

Snap fold. Someone overbetting the pot on that turn into 3 other people CERTAINLY has TT beaten. I'd fold AA here.
