as long as they are unconfirmed, the bitcoin is still considered owned by you
if you want you can abandon the txs on your wallet and wait out a few days for most nodes to drop them
then you can resend again and don't forget to add sufficient fee
if you don't want to wait you can try broadcast the new tx and attempt double spend
though it would be a bit harder to do because you need to find nodes that would accept that double spend tx
