Need Poker help

Hi all,

I need some blonde advice and I hope you'll all help me out. One of my problems when playing MTTs is the finish. I know how to play a steady game and how to build stacks early on and play a solid game to make it to the final table but when it gets down to 3, 4, 5 left I would like some advice on playing hands when you get dealt garbage....in last nights VC P4C MTT the highest hand I had from 6 deals was 8-7 off, 8-4, 3-2, 2-2 all rubbish. Was I just dealt rubbish hands? should I have played these strong? should I have limped to see if I'd hit a flop? should I have re-raised each pot regardless of the rubbish I held?

I was chip leader when we were down to 4 and flopped a straight draw with an ace on the board and 2 diamonds. I had no flush draw but bet out like I had. I was 90% confident that my opponent had A-rag. The turn came another diamond. Oppo bet out so i re-raised him - had straight draw still and possible flush / flush draw on the table and he still called. River came as no help but still re-raised large hoping to push him off the pot be he still called showing an A2 hitting his 2 on the river to make 2 pair. I had lost 3/5 of my stack. I had played a tight solid game up until this point, protecting my stack, making sharp stabs at the pot where i could. Did I play the hand wrong? IMO I showed aggression and strength but still got called and lost.
