Wait for miners to eventually pick it up

Wait until node mempools forget the tx and return it to you, which will eventually happen, because each node’s mempool is not infinite in space, but rather limited to 300MB typically. When the mempool reaches full capacity, nodes get rid of the lowest fee tx's in order to add higher fee tx's. Once this happens, the funds in your limbo tx become accessible again

Create a new wallet that supports RBF (Replace by Fee) using your existing seed, then replace the tx
