I've pushed it to antpool, but chances of it getting confirmed this way are slim, as antpool is currently being abused... Since this transaction only has a fee of 55 sat/byte, you have only a few options:
1) wait it out, the transaction will either be confirmed sooner or later, if it isn't confirmed it'll probably get dropped and the unspent outputs can be re-used
2) if you're either the sender and there was a change address, or if you're the receiver, you can do a CPFP
3) if you were the sender, you can double spend the inputs of this unconfirmed transaction
4) you can pay a mining pool to include your tx in the blocks they're currently working at
