Can I verify my own transaction?
Yes, there exist two possibilities to release your stuck transactions using Fee Bumping:

This page gives exact instructions on how to increase the fee on a transaction that is currently stuck in order to make it unstuck. This is always done by creating a new transaction that will either spend the coins sent by the stuck transaction (called child-pays-for-parent, or CPFP) or replace the stuck transaction (called replace-by-fee, or RBF).

Edit: I recommend consulting Johoe's Mempool Statistics next time before you broadcast a new transaction.
