You can try contacting either quickseller or macbook-air and offering a small payment for them to get your transaction confirmed. They don't charge much and can get F2Pool to confirm your transaction.
You can contact them through these links.

I faced a similar issue a few days back transaction not getting confirmed due to low fee but user "QuickSeller" got my transaction confirmed in minutes when I sent him 0.0001 BTC. He has access to some pool . PM him.
Quickseller will push your transaction using F2pool, so when it mines another block your transaction will probably get confirmed. You can see the times it mined its latest blocks here.
