Transaction unconfirmed - day 12!
This question is another duplicate and already answered here by dooode:
Why is my transaction not getting confirmed and what can I do about it?

You have to stop/reverse the old Bitcoin transaction you created without confirmations:
Make a backup of your wallet.dat

Run bitcoind or bitcoin-qt with -zapwallettxes=1 option.

This makes the wallet "forget" any unconfirmed transactions, thus enabling you to reuse their inputs.
Create a new transaction to make your payment and add an appropriate fee this time.

You can now send the bitcoins where ever you want or you can send them all back to yourself.
