Fold 3BET pre in a Multy way Pot with QKs?

Poker Stars, $0.23 Buy-in (15/30 blinds, 4 ante) No Limit Hold'em Tournament, 9 Players
SORRY,BECAUSE I COULDNT CONVERT THE HAND TO A EASIEST VISUALIZATION
It was the EARLY stages.i had 20% Pot Odds on Turn and by counting the Outs i believed that they were waiting a Draw(Flush or Straight because the UTG 3BETED,it was probably some AJ+) and my Odds to hit the flus Plus The Gutshot and the Overcards gave me -+ 33% equity

IT WAS BETTER FOLD PRE OR  WAS WELL PLAYED?
