Yeah... your first transaction has 0 fee... so that's not likely to go anywhere fast... and the 2nd one spends the output from the first... so that cannot confirm until the first one does

What wallet did you use to send these? You need to make sure your wallet is not rebroadcasting them and wait for the transactions to drop from the mempool (could take up to 14 days if no one rebroadcasts them)... then you should be able to spend the coins again.
