I have read the stickied topic about this and it suggested that I delete the transaction from my wallet using pywallet and resend the transaction with a fee. Can anyone tell me what happens to the bitcoins from the original transaction? Will it come back to my wallet?

Another question. After sending the above 0 fee transaction which shows unconfirmed on blockchain.info, i sent two other transactions, one with 0 fee and another with a VERY small fee. These two subsequent transactions are not showing up at all on blockchain.info. Should I follow the same procedure as with 0 confirmations and delete the transaction from my wallet? I am using bitcoin core v0.12.1 if it matters.

Thanks in advance for any help.
