Blew it late again - i suck at poker

Played a bunch of tourneys yesterday to help pass the day and went deep in the Full Tilt 109.00 35K Guar. Labor Day special. It drew 631 entrants which meant the top 63 got paid. With 23 left, I was dead last in chips lol. But a few double ups and a stop and go and I was chip leader with 12 to go. I had over 300K in chips (you start with 3000) and the nearest guy had 200K. I ran a gross bluff that didn't work vs. the best player at the table and went card dead at the final table and finished 5th for $4100.00. Pretty disappointing when 1st was over 15K, but I'm pretty happy with the way I played, just couldn't get anything together at the final table.
