Was the Replace By Fee option enabled for this transaction? If not, you won't be able to increase the fee for the transaction and would receive an error.

You may wish to try and use ViaBTC's accelerator ( https://www.viabtc.com/tools/txaccelerator/ ) to help speed up the confirmation of this time. The service is usually full so you will have to try at the beginning of each hour when it resets until you can get your transaction in.

If RBF was not activated you could double spend it with a higher fee.

You would need to connect to an Electrum server which does not have your transaction in the mempool anymore (just try a few until your transaction does not show up in the history anymore) and create a second transaction with the same input(s) as with the first.

Edit: older bitcoind versions remove old transactions after 3 days, newer ones only after 14 days.
