UB Turbo - Final 2 tables

[pavement]

Okay, I am in the final 20 of a field of around 300 in a UB Turbo. I am middle of the pack (with a little over 1/2 of avg stack)with about 8,000 chips (after I pay BB this hand) but blinds are 1000/2000 with 250 (I think) antes, so I'm in push or fold mode. I am BB and get 5 5. MP raises 6k. He has me covered by a couple of thousand and hasn't been very aggressive to this point. If I push, of course he will call. Do you fold with only 4xBB remaining or push? To me, it seemed like a fairly easy push but now I'm not so sure. What's troubling me is that everyone is also in my same boat and I am middle of the pack. Fold equity will be low obviously but should I have waited to open push? He had a higher PP as I had feared but I was hoping he just had 2 overs.
