Omaha rebuy .. made the money again

Things are looking up made 4th place in my omaha rebuy ........ got $57.20 ... ( top 5 got paid to day as there was only 42 entrants ) ..... a good game ... wasn't a crazy start .... which is usually the case in rebuys ..... didn't win many hands in the first hour but i had 4,500 chips by the break so i purchased a add on to bring me up to 6,500 ....... the next 45 minutes were uneventful i didn't loose or gain any chips then I had a nice spell for about 15 minutes which took me up to 20,000 chips ...... and then we were down to the final table ..........i managed to get up to 30,000 by the time we hit the final 5 but then it started to go wrong ....... we lost 1 more player leaving 4 of us ... and my chips started to dwindle away ....... not being helped by the blinds which were 1,000 2,000 and finally down to my last hand I was in the big blind with 12,000 chips the first to act made a minimum raise the small blind called ..... i hadn't much of a hand but it made no sense to fold to a minimum raise so i called the extra 2,000 chips ..... the flop came 2,7,8 ..I had a 5,6 in my hand so i pushed all in with my last 8,000 chips ..... the person who raised called and the other player folded...... .... but nothing came on the turn or river to help me ......he had a pair of queens in his hand and that was good enough to win the hand and send me packing.
