Lost in the wilderness - help required

Hi folks

I have a legacy Litecoin-QT wallet which I have held since 2013.

Recently I downloaded an Exodus IO wallet and transferred my Litecoins over such that I could trade them if needed for some of the emerging currencies.

I transferred them in early June and they are showing in my Exodus wallet (after a spell of disappearing). However I am unable to trade them. When I go back to my Litecoin QT wallet they are missing but the transactions are unconfirmed in the blockchain.

Since then I understand that the problem is because the old wallet I originally sent from didn’t automatically apply a fee for the blockchain to collect for verification. I now seem to be in limbo with no plan to be able to confirm the transaction.

Any help would be much appreciated.
