Kings in a typical bad situation? Evaluate this play please.

[Thomas Newton]

I'm new to the table, happy to find kings, not too happy to have this many players, a raise in front and an unfriendly flop. The raise on the turn put me even more on the defensive.

Am I a wuss or appropriately cautious here?
