Which wallet are you using? The bitcoin-core wallet has a couple of options to either zap mempool transactions or increase the fee on an existing transaction.

I'm not familiar with that wallet. On the Bitcoin core wallet you can right click a transaction and choose "Increase transaction fee". To do that the transaction must have had the "Replace by fee" checkbox ticked when it was created.

## 1. You could try child-pays-for-parent.

Your unconfirmed transaction with the txid `4e19db9b29dffd508073dd5d67ad8096559e28ef92da0eeb28fe85756396858c` has two ouputs.

You can use that change output as an input for a new transaction where you pay a high fee. Miners will then be interested to mine that new transaction but they can only if they also mine the old one (txid above).

You may use 2x the recommended

## 2. Double-Spend (harder)

* Use `-zapwallettxes=1` as Bitcoin Core startup argument.
* Use CoinControl (enable it via Bitcoin-Qt settings)
* Select your "blocked" input (`1KDcKTBTLWnLUED6yMA4Huj5CfzgKfuvJF` from `7aa1366669c3c836d7bf7abbc9b934af62bf669a250b66ccd2d72197aeafee35` 0.0995BTC) in CoinControl and do a new transaction
