I've rewritten your transactions OP to remove the dust input, keep the payment output the same, and very slightly adjusted the fee so you can replace your currently unconfirmed transaction:


If you can sign this and broadcast it to a node which accepts full RBF replacements, then it should replace your other transaction and be confirmed fairly quickly. You can do this easily with Electrum if you are able to import your wallet to Electrum using either your seed phrase or a private key for that address. You should do this on an airgapped device for security reasons.

Otherwise, at the effective fee rate of ~7.5 sats/vbyte, you are going to be waiting weeks for a confirmation.

The parent transaction with a fee rate of 6 sats/vbyte will already have been dropped by default nodes, meaning OP's should have been dropped as well. There are however an increasing number of nodes using non-default mempool settings, which is why we can still see OP's transaction on block explorers and he can still see it in his wallet.
