Aside from the suggestion above, you can use transaction accelerator to atleast hasten it's confirmation.
It's almost no use though of your transaction fee was 1 satoshi and if the mempool is heavily trafficked, but mempool is good now, just wait a little while if you can't add fee to your tx.
Mempool is heavily trafficked now. +40k unconfirmed transaction.
Viabtc say too low fee ;/
