Thank you.
So if waiting for it to drop off the network may not work as someone else may keep rebroadcasting the TX, what can I do to get this TX through? I have heard I could possibly rebroadcast it with a higher fee, but my wallets won't let me because it considers the funds spent already.
If you had the private key of your wallet try to recover it in other wallet like electrum. I think once you send your bitcoin address only the network can rebroadcast your transaction.
If you use electrum wallet i think you can have more option to do some ways to push your transaction.
You can rebroadcast it here
