Your second transaction depends on the first transaction, so it cannot confirm until the first one does. Your first transaction pays a relatively low fee rate of ~57 satoshis/byte. According to
https://bitcoinfees.github.io/#30m the current recommended fee rate to confirm within the next block is 180 satoshis/byte.
You have a few options here. You can wait and hope it confirms, wait for the transaction to be "forgotten" by the network, attempt a double spending transaction that pays a higher fee, or ask a miner to confirm it for you.
For the third option, we need to know what wallet software you are using.
