So I recently found some bitcoin on a bitcoin-qt wallet that I hadn't used in a while. My plan was to send all of it to my coinbase account for now since I won't have access to this computer in a couple months. I first sent  it using a stupidly low fee (something like 20 sat/byte) and it of course never got confirmed, so I abandoned the transaction using bitcoin-qt. I sent it again a couple days ago using a fee of about 400 sat/byte, but it still has 0 confirmations and https://bitcoinfees.earn.com/ suggests that I should really be using 630 sat/byte, at the time of this post at least.

The problem is that all of my transactions in bitcoin-qt were greyed out and I couldn't abandon the stuck one, so I ran the client again using -zapwallettxes, which cleared all of my transactions but now it says I have a balance of 0.00000000BTC!

Here's a link to the transaction: https://live.blockcypher.com/btc/tx/dd803ddb0e51e5461b328f27b2eccf0201b7ccb7a294b56e6f6551539a4e2fdd/

It mentions that it is a double-spent transaction, but I don't really care since I am trying to send all of the BTC from the wallet, so it can't exactly take more BTC than is actually there. I'm running a rescan of the blockchain right now but that obviously takes a while. Any tips on how to unstick this transaction?
