TPTK but too many people

Okay I have TPTK but I REALLY don't like it against 5 other hands that have passively called me the whole way. Is it too weak to not bet this? Should I really bet/fold against this many players? I may be ahead on this hand but can I statistically be ahead enough for it to be +ev???
