I can't find this transaction on blockexplorers (check blockchain.info and blockcypher) that means the transaction has been forgotten by the network or in other words dropped out of mempool.
in other other words, the funds are back in your wallet and you can sped them again.
Actually chain.so still has it. From what I see he has spent 10 sat/byte.
I don't know an easy way to double spend; the usually proposed way is with Bitcoin Core and I certainly don't have the patience to explain if he didn't have the patience to do a google search before asking a question that's asked almost daily.
With this fee it would hazardous to estimate "how much more", but according to
https://btc.com/stats/unconfirmed-tx it could be in some 12-24h unless it's dropped completely by the network and returns to your wallet.
(OP, if you go to the site I've shown you, you'll see that the network was very busy last few days, so the fee was way too low.)
